Introduction

In this article, we will simplify the given expression (14ab)−2\left(\frac{1}{4ab}\right)^{-2}, assuming that a≠0a \neq 0 and b≠0b \neq 0. We will use the properties of exponents and fractions to simplify the expression.

Understanding the Expression

The given expression is (14ab)−2\left(\frac{1}{4ab}\right)^{-2}. This expression involves a fraction raised to a negative power. To simplify this expression, we need to understand the properties of exponents and fractions.

Properties of Exponents

When a fraction is raised to a negative power, we can rewrite it as the reciprocal of the fraction raised to the positive power. In other words, (ab)−n=(ba)n\left(\frac{a}{b}\right)^{-n} = \left(\frac{b}{a}\right)^n.

Simplifying the Expression

Using the property of exponents mentioned above, we can rewrite the given expression as:

(14ab)−2=(4ab1)2\left(\frac{1}{4ab}\right)^{-2} = \left(\frac{4ab}{1}\right)^2

Now, we can simplify the expression by squaring the numerator and denominator:

(4ab1)2=(4ab)212\left(\frac{4ab}{1}\right)^2 = \frac{(4ab)^2}{1^2}

Expanding the numerator, we get:

(4ab)212=16a2b21\frac{(4ab)^2}{1^2} = \frac{16a^2b^2}{1}

Final Answer

The final answer is 16a2b21\boxed{\frac{16a^2b^2}{1}}. However, we need to choose the correct answer from the options provided.

Comparing with Options

Let's compare our final answer with the options provided:

A. −116a2b2-\frac{1}{16a^2b^2} B. a2b24\frac{a^2b^2}{4} C. −16a2b2-16a^2b^2 D. 16a2b216a^2b^2

Our final answer is 16a2b21\frac{16a^2b^2}{1}, which is equivalent to 16a2b216a^2b^2. Therefore, the correct answer is:

The Correct Answer is D. 16a2b216a^2b^2

Conclusion

In this article, we simplified the expression (14ab)−2\left(\frac{1}{4ab}\right)^{-2} using the properties of exponents and fractions. We rewrote the expression as the reciprocal of the fraction raised to the positive power and then simplified it by squaring the numerator and denominator. Our final answer is 16a2b216a^2b^2, which is equivalent to option D.
