(1/27)^-2/3
equal to​

Answer 1

$= > {\bigg( \frac{1}{27} \bigg )}^{ \frac{ - 2}{3} } \\ \\ \\ = > {(27)}^{ \frac{2}{3} } \: \: \: \: \: \: \: \: \rm \{ \because {a}^{ - m} = {(1/a)}^{m} \} \\ \\ = > {\bigg \{ {(27)}^{2} \bigg \}}^{ \frac{1}{3} } \: \: \: \: \: \: \: \: \rm \{ \because {a}^{m/n} = {({a}^{m})}^{1/n} \} \\ \\ = > \sqrt[3]{ {27}^{2} } \\ = > \sqrt[3]{729} \\ = > 9$
