Answer 1

Resposta:

$a) \frac{1}{ \sqrt{2} } = \frac{1}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{ \sqrt{2} }{2} \\ \\ b) \frac{2}{ \sqrt[3]{4} } = \frac{2}{ \sqrt[3]{ {2}^{2} } } \times \frac{ \sqrt[3]{ {2}^{1} } }{ \sqrt[3]{ {2}^{1} } } = \sqrt[3]{2}$

$c) \frac{2}{ \sqrt[4]{8} } = \sqrt[4]{2}$
