Answer 1

Resposta:

a)  $\sqrt[3]{\frac{-8}{125} } = \frac{\sqrt[3]{-8} }{\sqrt[3]{125} } = \frac{-2}{5}$

b) $\sqrt[3]{27} =3$

c) $\sqrt{75} *\sqrt{12} = \sqrt{75*12} =\sqrt{900}=30$

d) $\sqrt[3]{216}=6$

e) $\frac{\sqrt{20} }{\sqrt{5} } =\sqrt{\frac{20}{5} } =\sqrt{4} =2$

f) $\sqrt{\sqrt[3]{64} }=\sqrt{4}=2$

g) $\sqrt{5\sqrt[4]{256} } = \sqrt{5*4} =\sqrt{4} *\sqrt{5} =2*\sqrt{5}$
