​

Answer 1

Explicação passo-a-passo:

a)

$\sf \dfrac{\sqrt[5]{9}}{\sqrt[5]{3}}=\dfrac{\sqrt[5]{3}\cdot\sqrt[5]{3}}{\sqrt[5]{3}}=\sqrt[5]{3}$

b)

$\sf \dfrac{\sqrt{12}}{\sqrt{2}}=\dfrac{\sqrt{2}\cdot\sqrt{6}}{\sqrt{2}}=\sqrt{6}$

c)

$\sf \dfrac{\sqrt[4]{36}}{\sqrt[5]{12}}=\dfrac{\sqrt[4]{12}\cdot\sqrt[4]{3}}{\sqrt[4]{12}}=\sqrt[4]{3}$
