${(5 x^{- \frac{1}{2}})}^{- 2}$

Step 1

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

${(5 \frac{1}{x^{\frac{1}{2}}})}^{- 2}$

Step 2

Combine $5$ and $\frac{1}{x^{\frac{1}{2}}}$ .

${(\frac{5}{x^{\frac{1}{2}}})}^{- 2}$

Step 3

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

${(\frac{x^{\frac{1}{2}}}{5})}^{2}$
