Racionalizar >>>  $\frac{2}{ \sqrt[7]{3 ^{4} } }$

Answer 1

$\frac{2}{ \sqrt[7]{3^4} } = \frac{2}{ \sqrt[7]{3^4} } \cdot \frac{\sqrt[7]{3^3} }{ \sqrt[7]{3^3} } =\frac{2\sqrt[7]{3^3} }{ \sqrt[7]{3^4\cdot3^3} } =\frac{2\sqrt[7]{3^3} }{ \sqrt[7]{3^{4+3}} } =\frac{2\sqrt[7]{3^3} }{ \sqrt[7]{3^7} } =\frac{2\sqrt[7]{27} }{ 3}}$
