Deconstructing the Expression: A Step-by-Step Approach

Before we dive into the calculations, it's crucial to understand the structure of the expression we're dealing with: √(2160x⁸ / 60x²). This expression involves a square root, a fraction, and variables raised to exponents. To simplify it effectively, we'll break it down into smaller, manageable parts. First, we'll focus on simplifying the fraction inside the square root. This involves finding the greatest common divisor (GCD) of the coefficients (2160 and 60) and simplifying the variables using the rules of exponents. The essence of simplification lies in identifying and canceling out common factors. Once the fraction is simplified, we'll tackle the square root. Recall that the square root of a fraction is the fraction of the square roots. This allows us to separate the square root of the numerator from the square root of the denominator. Finally, we'll apply the rules of radicals to simplify the square roots of the numerical and variable terms. This might involve factoring out perfect squares from the radicand (the expression under the radical sign) and applying the property √(a*b) = √a * √b. By meticulously following these steps, we'll gradually transform the complex expression into its simplest, most elegant form. This systematic approach not only ensures accuracy but also enhances our comprehension of the underlying mathematical principles.

Simplifying the Fraction: Unveiling the Core Components

The first crucial step in simplifying √(2160x⁸ / 60x²) is to address the fraction within the square root. This involves simplifying both the numerical coefficients and the variable terms. Let's begin with the numerical coefficients, 2160 and 60. To simplify the fraction 2160/60, we need to find the greatest common divisor (GCD) of 2160 and 60. The GCD is the largest number that divides both 2160 and 60 without leaving a remainder. By performing prime factorization or using the Euclidean algorithm, we can determine that the GCD of 2160 and 60 is 60. Now, we can divide both the numerator and the denominator by 60: 2160 / 60 = 36 and 60 / 60 = 1. Therefore, the simplified numerical fraction is 36/1, which is simply 36. Next, let's focus on the variable terms, x⁸ and x². To simplify the fraction x⁸ / x², we'll employ the quotient rule of exponents, which states that xᵃ / xᵇ = xᵃ⁻ᵇ. Applying this rule, we get x⁸ / x² = x⁸⁻² = x⁶. By simplifying both the numerical and variable parts of the fraction, we've transformed 2160x⁸ / 60x² into 36x⁶. This simplified fraction now forms the core of our expression under the square root, making it significantly easier to handle. This reduction process is vital for simplifying complex expressions and revealing their underlying simplicity.

Taming the Square Root: Extracting the Essence of Radicals

With the fraction inside the square root now simplified to 36x⁶, our expression has transformed into √(36x⁶). The next step is to tackle the square root itself. Recall that the square root of a product is the product of the square roots, i.e., √(ab) = √a * √b. Applying this property, we can rewrite √(36x⁶) as √36 * √x⁶. Now, let's evaluate each square root separately. The square root of 36 is 6, since 6 * 6 = 36. For √x⁶, we need to remember that taking the square root is the inverse operation of squaring. In other words, we're looking for an expression that, when squared, equals x⁶. Using the power of a power rule of exponents, (xᵃ)ᵇ = xᵃᵇ, we can see that (x³) ² = x³*² = x⁶. Therefore, √x⁶ = x³. By evaluating both square roots, we've found that √36 = 6 and √x⁶ = x³. Now, we can combine these results to get the simplified expression: √36 * √x⁶ = 6 * x³ = 6x³. This elegant result represents the simplified form of the original expression. The extraction of the square root highlights the power of inverse operations in mathematics and our ability to manipulate expressions to reveal their fundamental nature.

The Grand Finale: Presenting the Simplified Form

After meticulously simplifying the original expression √(2160x⁸ / 60x²), we have arrived at the grand finale: the simplified form. Through a series of strategic steps, including simplifying the fraction, applying the rules of exponents, and extracting square roots, we have transformed the seemingly complex expression into its most elegant and concise form. As we demonstrated in the previous sections, the expression √(2160x⁸ / 60x²) can be simplified as follows:

  1. Simplify the fraction: 2160x⁸ / 60x² = 36x⁶
  2. Apply the square root: √(36x⁶) = √36 * √x⁶
  3. Evaluate the square roots: √36 = 6 and √x⁶ = x³
  4. Combine the results: 6 * x³ = 6x³

Therefore, the simplified form of √(2160x⁸ / 60x²) is 6x³. This final result elegantly captures the essence of the original expression, stripped of its initial complexity. This process exemplifies the beauty and power of mathematical simplification, where intricate expressions can be transformed into their most fundamental forms. This final presentation of the simplified form underscores the importance of a systematic approach and the elegance of mathematical solutions.

Dissecting the Answer Choices: Identifying the Correct Solution

Now that we've meticulously simplified the expression √(2160x⁸ / 60x²) to 6x³, let's examine the given answer choices and identify the correct one. The answer choices provided are:

A. 36x³ B. 36x² C. 6x³ D. 6x²

By comparing our simplified form, 6x³, with the answer choices, we can clearly see that option C, 6x³, matches our result perfectly. The other options, 36x³, 36x², and 6x², are incorrect. Option A, 36x³, has the correct variable term but an incorrect coefficient. Option B, 36x², has an incorrect coefficient and an incorrect variable term. Option D, 6x², has the correct coefficient but an incorrect variable term. Therefore, the only answer choice that aligns with our simplified expression is C. This process of answer choice dissection is crucial in mathematics for confirming the correctness of our solution and eliminating any potential errors. It reinforces the importance of careful calculation and attention to detail.

Common Pitfalls and How to Avoid Them: A Guide to Error-Free Simplification

Simplifying radical expressions can sometimes be tricky, and it's easy to fall into common pitfalls if you're not careful. To ensure error-free simplification, let's explore some common mistakes and how to avoid them. One frequent mistake is incorrectly simplifying fractions. When simplifying fractions, it's crucial to find the greatest common divisor (GCD) of the numerator and denominator and divide both by it. Forgetting to simplify the fraction completely can lead to incorrect results. Another common error occurs when applying the rules of exponents. For example, when dividing variables with exponents, remember to subtract the exponents (xᵃ / xᵇ = xᵃ⁻ᵇ), not divide them. Similarly, when taking the square root of a variable raised to an exponent, remember to divide the exponent by 2 (√xᵃ = xᵃ/²). A significant pitfall lies in incorrectly applying the property √(a*b) = √a * √b. This property is valid for multiplication, but it does not apply to addition or subtraction. For example, √(a + b) ≠ √a + √b. Furthermore, neglecting to consider the absolute value when taking the square root of a variable expression can lead to errors. For instance, √(x²) = |x|, not just x. To avoid these pitfalls, always double-check your calculations, meticulously apply the rules of exponents and radicals, and be mindful of the properties of square roots. By being aware of these common mistakes and taking precautions to avoid them, you can significantly enhance your accuracy and confidence in simplifying radical expressions. This error-prevention guide serves as a valuable tool for mastering the art of simplification and achieving consistent success.
