${(\frac{3 z^{5}}{4 x^{- 5} y^{3}})}^{- 2}$

Step 1

Move $x^{- 5}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

${(\frac{3 z^{5} x^{5}}{4 y^{3}})}^{- 2}$

Step 2

Change the sign of the exponent by rewriting the base as its reciprocal.

${(\frac{4 y^{3}}{3 z^{5} x^{5}})}^{2}$

Step 3

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