Understanding equivalent expressions is a cornerstone of mathematical proficiency. In essence, equivalent expressions are mathematical statements that, despite their differing forms, yield the same result when evaluated. This concept is not merely an abstract idea; it has practical applications across various mathematical domains, from simplifying complex equations to solving intricate problems. Consider, for instance, the expression ${2x + 4}$. An equivalent expression could be ${2(x + 2)}$. While they appear different, both expressions produce identical values for any given value of ${x}$. This equivalence allows mathematicians and problem solvers to manipulate expressions into more manageable forms, facilitating easier calculations and clearer understanding. The ability to recognize and derive equivalent expressions is particularly vital in algebra, calculus, and beyond, where simplifying expressions can significantly reduce the complexity of a problem. Furthermore, this skill fosters a deeper comprehension of mathematical structures, enabling a more intuitive approach to problem-solving. As we delve into the specifics of finding an expression equivalent to ${\frac{4 f^2}{3} + \frac{1}{4 f}}$, we will see how these fundamental principles of equivalent expressions come into play, transforming seemingly complicated problems into manageable and solvable tasks.

The question at hand requires us to find an expression equivalent to ${\frac{4 f^2}{3} + \frac{1}{4 f}}$. This involves combining two fractions with different denominators into a single, simplified expression. The challenge lies in identifying the correct algebraic manipulations needed to achieve this. We must first find a common denominator for the two fractions, then adjust the numerators accordingly, and finally combine them. This process will involve basic algebraic principles, such as finding the least common multiple (LCM) of the denominators and applying the distributive property. Successfully navigating this problem will demonstrate an understanding of fraction manipulation and algebraic simplification, core skills in mathematics.

Before diving into the solution, it's crucial to deconstruct the given expression ${\frac{4 f^2}{3} + \frac{1}{4 f}}$ and understand its components. The expression consists of two terms, each a fraction involving the variable ${f}$. The first term, ${\frac{4 f^2}{3}}$, is a rational expression where ${4f^2}$ is the numerator and ${3}$ is the denominator. The second term, ${\frac{1}{4 f}}$, also a rational expression, has a numerator of ${1}$ and a denominator of ${4f}$. The core task is to add these two fractions together, which requires a common denominator. The denominators, ${3}$ and ${4f}$, are different, necessitating the identification of their least common multiple (LCM). Understanding the structure of the expression and the role of each term is the first step towards finding an equivalent, simplified form. By recognizing the individual components and their relationships, we can strategically plan the subsequent algebraic manipulations. This initial deconstruction not only simplifies the problem-solving process but also enhances our comprehension of the underlying mathematical principles. As we proceed, we will see how this foundational understanding guides us through the necessary steps to arrive at the correct equivalent expression.

The initial step in simplifying ${\frac{4 f^2}{3} + \frac{1}{4 f}}$ involves finding a common denominator for the two fractions. The denominators are ${3}$ and ${4f}$. The least common multiple (LCM) of these two terms is ${12f}$. Once we have the common denominator, we need to rewrite each fraction with this new denominator. This involves multiplying both the numerator and the denominator of each fraction by the appropriate factor that will result in the common denominator. For the first fraction, ${\frac{4 f^2}{3}}$, we multiply both the numerator and the denominator by ${4f}$, resulting in ${\frac{16 f^3}{12f}}$. For the second fraction, ${\frac{1}{4 f}}$, we multiply both the numerator and the denominator by ${3}$, resulting in ${\frac{3}{12f}}$. Now that both fractions have the same denominator, we can combine them by adding their numerators. This step is crucial in simplifying the original expression and moving closer to the final answer. The process of finding a common denominator and adjusting the fractions accordingly is a fundamental technique in algebra, applicable in various contexts beyond this specific problem. By mastering this technique, one can confidently tackle more complex algebraic manipulations and simplifications. The next step will involve adding the adjusted fractions and further simplifying the resulting expression.

Having established the common denominator of ${12f}$, we now proceed to combine the fractions. The first fraction, ${\frac{4 f^2}{3}}$, was transformed into ${\frac{16 f^3}{12f}}$, and the second fraction, ${\frac{1}{4 f}}$, became ${\frac{3}{12f}}$. To combine these fractions, we add their numerators while keeping the common denominator. This gives us the expression ${\frac{16 f^3 + 3}{12f}}$. The addition of the numerators is a straightforward process, but it’s essential to ensure that like terms are combined correctly. In this case, ${16 f^3}$ and ${3}$ are not like terms, so they remain separate in the numerator. The resulting fraction, ${\frac{16 f^3 + 3}{12f}}$, represents the combined form of the original expression. This step is a critical point in the simplification process, as it brings the two separate fractions together into a single expression. However, the process of simplification is not yet complete. The next step involves examining the resulting fraction to determine if any further simplification is possible. This might involve factoring, canceling common factors, or other algebraic manipulations. By carefully reviewing the combined fraction, we ensure that the final answer is in its simplest and most accurate form. The ability to combine fractions with different denominators is a fundamental skill in algebra, and mastering this step is essential for success in more advanced mathematical topics.

Now, let's perform the detailed calculation to arrive at the equivalent expression. We start with the expression ${\frac{4 f^2}{3} + \frac{1}{4 f}}$. As established, the least common multiple (LCM) of the denominators ${3}$ and ${4f}$ is ${12f}$. We rewrite each fraction with this common denominator:

First fraction: ${\frac{4 f^2}{3} = \frac{4 f^2 \times 4f}{3 \times 4f} = \frac{16 f^3}{12f}}$

Second fraction: ${\frac{1}{4 f} = \frac{1 \times 3}{4 f \times 3} = \frac{3}{12f}}$

Now, we add the two fractions:

${ \frac{16 f^3}{12f} + \frac{3}{12f} = \frac{16 f^3 + 3}{12f} }$

The resulting expression is ${\frac{16 f^3 + 3}{12f}}$. This fraction represents the simplified form of the original expression. To ensure that this is indeed the simplest form, we check for any common factors between the numerator and the denominator. In this case, there are no common factors that can be canceled out, and the numerator cannot be factored further. Therefore, ${\frac{16 f^3 + 3}{12f}}$ is the equivalent expression we were seeking. This detailed calculation demonstrates the step-by-step process of combining fractions with different denominators and simplifying the result. Each step is crucial in ensuring the accuracy of the final answer. The ability to perform these calculations accurately and efficiently is a key skill in algebra and is essential for solving more complex problems. By breaking down the problem into smaller, manageable steps, we can confidently arrive at the correct solution. The next section will discuss the final answer and compare it with the given options.

This situation underscores the importance of carefully reviewing both the problem-solving process and the given options. In this case, while the step-by-step solution is accurate, the absence of a matching option suggests a possible error in the question itself. It is crucial to recognize such discrepancies and, if possible, verify the question's validity. In a real-world scenario, this might involve consulting additional resources or seeking clarification from the source of the problem. The process of comparing the final answer with the given options is a vital step in problem-solving, ensuring that the derived solution aligns with the available choices and highlighting any potential errors or inconsistencies.
