Question

Alguem consegue resolver esta expressão 

(3x1/81)/∛9

Answer 1

$(3x1/81)/ \sqrt[3]{9} -> (3/81)/ \sqrt[3]{9} -> (1/27)/ \sqrt[3]{9} -> 1/\sqrt[3]{9}*27 = 0,0178$

Primeiro faz a multiplicação
Segundo simplifica a fração
Terceiro multiplica invertido pela raiz cúbica

Answer 2

$\frac{\frac{3\times1}{81}}{\sqrt[3]{9}}=\\\\\frac{1}{27}\div{\sqrt[3]{3^2}}=\\\\\frac{1}{27}\times\frac{1}{\sqrt[3]{3^2}}\times\frac{\sqrt[3]{3}}{\sqrt[3]{3}}=\\\\\frac{\sqrt[3]{3}}{27\times3}=\\\\\frac{3^{\frac{1}{3}}}{3^4}=\\\\3^{\frac{1}{3}-4}=\\\\\boxed{3^{\frac{-11}{3}}}$
