Question

please answer the 3rd one.......​

Answer 1

$\huge\red{\boxed{\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}}}$

(1)..
$\sqrt[4]{81} = \sqrt[4]{ {3}^{4} } = 3$
(2).....
$\sqrt[5]{32} = \sqrt[5]{ {2}^{5} } = 2$
(3)....
${ (\frac{8}{125}) }^{ \frac{ - 1}{3} } = { (\frac{2}{5} )}^{ - \frac{ - 3}{3} } = \frac{5}{2}$
(4)...

${0.027}^{ \frac{ - 2}{3} } = { ( {0.3}^{3})} ^{(\frac{ - 2}{3})} = {0.3}^{ - 2} = { \frac{9}{100} }^{ - 1} = \frac{100}{9}$
