$\sqrt[3]{10 {}^{3} } \\ \sqrt[3]{2 ^{9} } \\ \sqrt{2 {}^{4} } \\ \sqrt{7 ^{3} }$
​

Answer 1

Resposta:

Explicação passo a passo:

$Regra...$

$\sqrt[n]{a^{m} } =a^{\frac{m}{n} }$

$a)$

$\sqrt[3]{10^{3} } =10^{\frac{3}{3} } =10^{1} =10$

$b)$

$\sqrt[3]{2^{9} } =2^{\frac{9}{3} } =2^{3}=8$

$c)$

$\sqrt{2^{4} } =2^{\frac{4}{2} } =2^{2} =4$

$d)$

$\sqrt{7^{3} } =\sqrt{7^{2}.7 } =7\sqrt{7}$
