Answer 1

Hey friend,
Here is the answer you were looking for:
${( \frac{27}{125} )}^{ - \frac{2}{3} } \\ \\ = {( \frac{ {3}^{3} }{ {5}^{3} } )}^{ - \frac{2}{3} } \\ \\ = {( \frac{3}{5} )}^{3 \times - \frac{2}{3} } \\ \\ = {( \frac{3}{5} )}^{ - 2} \\ \\ = {( \frac{5}{3} )}^{2} \\ \\ = \frac{ {5}^{2} }{ {3}^{2} } \\ \\ = \frac{25}{9}$


Hope this helps!!!!
