Question

Preciso de ajuda... alguém sabe corretamente?

Answer 1

Vamos l!

a)

$^{3} \sqrt{32} = ^{3} \sqrt{2.2.2.2.2} = 2 .^{3} \sqrt{2.2} = 2.^{3} \sqrt{4}$

b)

$\sqrt[5]{1024} = \sqrt[5]{2.2.2.2.2.2.2.2.2.2} = 2.2 = 4$

c)

$\sqrt[3]{(3^{-1})^{5} } = \sqrt[3]{3^{-5} } = \sqrt[3]{\frac{1}{3}^{5} } = \sqrt[3]{\frac{1}{3}. \frac{1}{3}. \frac{1}{3}. \frac{1}{3}.\frac{1}{3}} = \frac{1}{3} . \sqrt[3]{\frac{1}{3}.\frac{1}{3}} = \frac{1}{3} . \sqrt[3]{\frac{1}{9} }$
