Question

me ajudem nessa questão pf ​

Answer 1

Resposta:

${a}^{ \frac{x}{y} } = \sqrt[y]{ {a}^{x} }$

$a) \\ (0.09 {)}^{ \frac{1}{3} } = \\ \sqrt[3]{0.09} \\ \\ b) \\ ( - 0.4 {)}^{ \frac{3}{7} } = \\ \sqrt[7]{( - 0.4 {)}^{3} } \\ \\ c) \\ ( \frac{2}{9} {)}^{ \frac{1}{5} } = \\ \sqrt[5]{ \frac{2}{9} } \\ \\ d) \\ ( \frac{3}{4} {)}^{ \frac{3}{2} } = \\ \sqrt[2]{( \frac{3}{4} } {)}^{3}$
