Question

alguém sabe alguma dessas pfv

Answer 1

d) $\sqrt[6]{256} = \sqrt[6]{2^8}= \sqrt[6]{2^6.2^2}=2 \sqrt[6]{2^2}=2 \sqrt[3]{2}$

$\sqrt[4]{243}= \sqrt[4]{3^5}= \sqrt[4]{3^4.3}=3 \sqrt[4]{3}$

$\sqrt[3]{27000} = \sqrt[3]{3^3.1000}=3 \sqrt[3]{10^3} =3 .10=30$

$\sqrt[6]{0,000064} = \sqrt[6]{ \frac{64}{1000000} } = \frac{ \sqrt[6]{2^6} }{ \sqrt[6]{10^6} } = \frac{2}{10} =0,2$
