${(\frac{6 \times 4^{n}}{4^{2 n + 1} + 2^{4 n + 1}})}^{n^{- 1}}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

${(\frac{6 \cdot 4^{n}}{4^{2 n + 1} + 2^{4 n + 1}})}^{\frac{1}{n}}$

Step 2

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.
