Question

Calcule:

$a. \sqrt[3]{0.027 = }$

$b. \: \sqrt[5] \frac{1}{1024} =$
$c. \: \sqrt[8] \frac{1}{256} =$
ME AJUDEM, POR FAVOOR!!​

Answer 1

Bom Dia,

$\sqrt[3]{0,027} =\sqrt[3]{\frac{27}{1000} } \\\\\sqrt[3]{\frac{27}{1000} }= \frac{\sqrt[3]{27} }{\sqrt[3]{1000} } \\\frac{\sqrt[3]{27} }{\sqrt[3]{1000} } =\frac{3}{10} \\\\\\\\\sqrt[3]{0,027}=\frac{3}{10} =0,3$

Refaz a B pois ficou "bugado", aí repondo.

Bons estudos!
