Question

I need help!! rewrite using only positive rational exponents (x^6/7)^-7/5 simplify your answer.

Answer 1

Use the rules:
\[
x^{-a}=\frac{1}{x^a}\\
(x^a)^b=x^{ab}
\]

Answer 2

is it x^6/5

Answer 3

It'd be:
\[
\left(x^\frac{6}{7}\right)^{-\frac{7}{5}}=x^{-\frac{6}{5}}=\frac{1}{x^\frac{6}{5}}
\]
