Racionalize
$2 \sqrt[5]{8}$

$9 \sqrt[4]{27}$
​

Answer 1

Boa tarde!

a)

$\frac{2}{ \sqrt[5]{8} } = \frac{2}{ \sqrt[5]{8} }. \frac{ \sqrt[5]{8} }{ \sqrt[5]{8} } = \frac{2 \sqrt[5]{8} }{8} = \frac{ \sqrt[5]{8} }{4}$

b)

$\frac{9}{ \sqrt[4]{27} } = \frac{9}{ \sqrt[4]{27} }. \frac{ \sqrt[4]{27} }{ \sqrt[4]{27} } = \frac{9 \sqrt[4]{27} }{27} = \frac{ \sqrt[4]{27} }{3}$

Espero ter ajudado!

Bons estudos!
