Question

calcule

$\sqrt[3]{ \frac{8}{27} }$
​

Answer 1

Explicação passo-a-passo:

$\sqrt[3]{{8\over27}} =\sqrt[3]{{2^3\over3^3}} ={2\over3}$

Answer 2

$\sqrt[3]{ \frac{8}{27} } = \\ \\ \frac{ \sqrt[3]{8} }{ \sqrt[3]{27} } = \\ \\ \frac{ \sqrt[3]{ {2}^{3} } }{ \sqrt[3]{ {3}^{3} } } = \\ \\ \frac{2}{3}$
