${(x^{\frac{1}{2}} y^{- \frac{2}{3}})}^{- 6}$

Step 1

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

${(x^{\frac{1}{2}} \frac{1}{y^{\frac{2}{3}}})}^{- 6}$

Step 2

Combine $x^{\frac{1}{2}}$ and $\frac{1}{y^{\frac{2}{3}}}$ .

${(\frac{x^{\frac{1}{2}}}{y^{\frac{2}{3}}})}^{- 6}$

Step 3

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

${(\frac{y^{\frac{2}{3}}}{x^{\frac{1}{2}}})}^{6}$
