pls answer question 3

pls answer question 3 (3) (27)-4

Dear student

{\{\sqrt[3]{\frac{1}{{(27)}^{- 4}}}\}}^{\frac{- 3}{2}} = {(\frac{1}{{(27)}^{- 4}})}^{\frac{1}{3} \times \frac{- 3}{2}} = {(\frac{1}{{(27)}^{- 4}})}^{\frac{- 1}{2}} = \frac{1}{27^{- 4 \times \frac{- 1}{2}}} = \frac{1}{27^{2}} = \frac{1}{729} Identity used : 1) {(a^{m})}^{n} = a^{mn}
