Question

Calcule:

a) raiz cúbica de 512
b)raiz quarta de 121
c)raiz quinta de 3,2.10 elevado a sexta potência

Answer 1

a) $\sqrt[3]{512} = \sqrt[3]{2^{6}.2^{2}} = 2^{2} \sqrt[3]{2^{2}} = 4 \sqrt[3]{4}$

b) $\sqrt[4]{121} = \sqrt[4]{11^{2}} = \sqrt{11}$

c) $\sqrt[5]{(3,2.10)^{6}} = 3,2.10\sqrt[5]{3,2.10} = 32\sqrt[5]{32}$
