Question

Racionalize o denominador

Answer 1

e)

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

f)

$\frac{25}{ \sqrt[5]{{5}^{2} } } \times \frac{ \sqrt[5]{ {5}^{3} } }{ \sqrt[5]{ {5}^{3} } } = \frac{25 \sqrt[5]{ {5}^{3} } }{ \sqrt[5]{ {5}^{5} } } = \frac{25 \sqrt[5]{125} }{5} = 5 \sqrt[5]{125}$
