Question

(Fuvest-SP) Determine o valor de :

$\boxed{ \sqrt[3]{ \frac{2^{28}+2^{30}}{10} } }$

Questão simples e divertida.

Answer 1

$\sqrt[3]{ \frac{2^{28}+2^{30}}{10} } \\ \\ \sqrt[3]{ \frac{2^{28}+2^{28}.2^2}{10} } \\ \\ \sqrt[3]{ \frac{2^{28}+2^{28}.4}{10} } \\ \\ \sqrt[3]{ \frac{5.2^{28}.}{10} } \\ \\ \sqrt[3]{ \frac{2^{28}.}{2} } \\ \\ \sqrt[3]{2^{27}} =2^{ \frac{27}{3}} =>2^9$
