Question

$\sqrt[2]{ {2}^{3} } =$
$\sqrt[4]{ {3}^{5} } =$
ajudaaaa!!!!!​

Answer 1

Explicação passo-a-passo:

A)

$\sqrt[2]{ {2}^{3} }$

$\sqrt{ {2}^{3} }$

$\sqrt{ {2}^{2} \times 2}$

$\sqrt{ {2}^{2} } \sqrt{2}$

$2 \sqrt{2}$

B)

$\sqrt[4]{ {3}^{5} }$

$\sqrt[4]{ {3}^{4} \times 3}$

$\sqrt[4]{ {3}^{4} } \sqrt[4]{3}$

$3 \sqrt[4]{3}$

Answer 2

$\tt{a)}~\sf{\sqrt[2]{2^3}=\sqrt[\diagdown\!\!\!\!2]{2^{\diagdown\!\!\!\!2}\cdot2}=2\sqrt{2}}\\\tt{b)}~\sf{\sqrt[4]{3^5}=\sqrt[\diagdown\!\!\!\!4]{3^{\diagdown\!\!\!\!4}\cdot3}=3\sqrt[4]{3}}$
