Understanding the Problem

The core of our mathematical quest lies in simplifying the expression (16x8y−12)12\left(16 x^8 y^{-12}\right)^{\frac{1}{2}}. This expression presents a combination of numerical coefficients, variables raised to exponents, and a fractional exponent acting upon the entire term. To unravel this, we must invoke the fundamental principles of exponents. Specifically, we'll be leveraging the power of a product rule, which states that (ab)n=anbn(ab)^n = a^n b^n, and the power of a power rule, which dictates that (am)n=amn(a^m)^n = a^{mn}. Furthermore, we need to understand how to handle negative exponents, recalling that a−n=1ana^{-n} = \frac{1}{a^n}. The fractional exponent of 12\frac{1}{2} signifies taking the square root. Therefore, our task involves not only simplifying the exponents but also finding the square root of the numerical coefficient. This requires a methodical approach, carefully applying each rule in the correct sequence. We must pay close attention to the order of operations and ensure that each simplification step is logically sound. By doing so, we can systematically transform the given expression into its most simplified equivalent form, revealing the correct answer among the provided options. The challenge is not merely about arriving at the solution but also about understanding the underlying mathematical principles that govern the transformation.

Step-by-Step Solution

To solve the expression (16x8y−12)12\left(16 x^8 y^{-12}\right)^{\frac{1}{2}}, we will meticulously apply the rules of exponents. First, we distribute the exponent 12\frac{1}{2} to each factor within the parentheses. This utilizes the power of a product rule, which states that (ab)n=anbn(ab)^n = a^n b^n. Applying this rule, we get:

1612⋅(x8)12⋅(y−12)1216^{\frac{1}{2}} \cdot (x^8)^{\frac{1}{2}} \cdot (y^{-12})^{\frac{1}{2}}

Next, we simplify each term individually. The term 161216^{\frac{1}{2}} represents the square root of 16, which is 4. For the variable terms, we apply the power of a power rule, (am)n=amn(a^m)^n = a^{mn}. Thus, (x8)12=x8⋅12=x4(x^8)^{\frac{1}{2}} = x^{8 \cdot \frac{1}{2}} = x^4, and (y−12)12=y−12⋅12=y−6(y^{-12})^{\frac{1}{2}} = y^{-12 \cdot \frac{1}{2}} = y^{-6}. Substituting these simplified terms back into the expression, we have:

4⋅x4⋅y−64 \cdot x^4 \cdot y^{-6}

Now, we address the negative exponent. Recall that a−n=1ana^{-n} = \frac{1}{a^n}. Therefore, y−6=1y6y^{-6} = \frac{1}{y^6}. Substituting this into our expression, we get:

4â‹…x4â‹…1y64 \cdot x^4 \cdot \frac{1}{y^6}

Finally, we combine the terms to arrive at the simplified expression:

4x4y6\frac{4x^4}{y^6}

This step-by-step approach, utilizing the power of a product rule, the power of a power rule, and the handling of negative exponents, leads us to the equivalent expression. By carefully applying each rule, we transform the original complex expression into a simplified and easily understandable form.

Analyzing the Options

Having derived the simplified expression 4x4y6\frac{4 x^4}{y^6}, we now turn our attention to the provided options to identify the correct match. The options presented are:

A. −4x4y6-4 x^4 y^6 B. −8x4y6-8 x^4 y^6 C. 4x4y6\frac{4 x^4}{y^6} D. 8x4y6\frac{8 x^4}{y^6}

By comparing our derived expression with the given options, we can clearly see that option C, 4x4y6\frac{4 x^4}{y^6}, precisely matches our simplified form. Options A and B introduce a negative sign and an incorrect power of yy, while option D has an incorrect coefficient. Therefore, only option C aligns with our calculated result. This process of comparing our solution with the provided choices is a crucial step in problem-solving, ensuring that we select the correct answer. It also reinforces our understanding of the simplification process, as we can see how the other options deviate from the correct solution. By carefully analyzing each option, we solidify our confidence in the accuracy of our answer. This methodical approach not only helps in solving this particular problem but also equips us with a valuable strategy for tackling future mathematical challenges.
