Introduction

In mathematics, simplifying expressions is a crucial skill that helps us solve problems efficiently and accurately. When dealing with exponents, it's essential to understand the rules of exponentiation to simplify complex expressions. In this article, we will focus on simplifying the expression $\left(64 n^{12}\right)^{-\frac{1}{6}}$ using the rules of exponentiation.

Understanding Exponents

Before we dive into simplifying the expression, let's review the basics of exponents. An exponent is a small number that is written above and to the right of a larger number, indicating how many times the larger number should be multiplied by itself. For example, $2^3$ means $2$ multiplied by itself $3$ times, which equals $8$ . When dealing with exponents, we need to follow the rules of exponentiation to simplify expressions.

Simplifying the Expression

To simplify the expression $\left(64 n^{12}\right)^{-\frac{1}{6}}$ , we need to apply the rules of exponentiation. The first step is to break down the expression into its prime factors. We can write $64$ as $2^6$ and $n^{12}$ as $n^{12}$ . Now, we can rewrite the expression as $\left(2^6 n^{12}\right)^{-\frac{1}{6}}$ .

Applying the Power Rule

The power rule states that when we raise a power to another power, we multiply the exponents. In this case, we have $\left(2^6 n^{12}\right)^{-\frac{1}{6}}$ . To simplify this expression, we need to apply the power rule. We can rewrite the expression as $2^{6 \cdot -\frac{1}{6}} n^{12 \cdot -\frac{1}{6}}$ .

Simplifying the Exponents

Now, we can simplify the exponents. We have $2^{6 \cdot -\frac{1}{6}}$ , which equals $2^{-1}$ . Similarly, we have $n^{12 \cdot -\frac{1}{6}}$ , which equals $n^{-2}$ .

Final Simplification

Now, we can simplify the expression further. We have $2^{-1} n^{-2}$ , which can be rewritten as $\frac{1}{2} n^{-2}$ . Since $n^{-2}$ is the same as $\frac{1}{n^2}$ , we can rewrite the expression as $\frac{1}{2} \cdot \frac{1}{n^2}$ .

Conclusion

In conclusion, simplifying the expression $\left(64 n^{12}\right)^{-\frac{1}{6}}$ requires us to apply the rules of exponentiation. We broke down the expression into its prime factors, applied the power rule, and simplified the exponents. Finally, we simplified the expression to $\frac{1}{2} \cdot \frac{1}{n^2}$ .
