Answer 1

Resposta:

Explicação passo-a-passo:

$\displaystyle \frac{42\sqrt[7]{6^4} }{\sqrt[7]{6^5} } =42.\sqrt[7]{\frac{6^4}{6^5} } =42\sqrt[7]{6^{(4-5)}} =42\sqrt[7]{6^{(-1)}}=42.\frac{1}{\sqrt[7]{6^}} =42.\frac{1}{\sqrt[7]{6^}}.\frac{\sqrt[7]{6^6}}{\sqrt[7]{6^6}} =\frac{42}{6} .\sqrt[7]{6^6}=\frac{21}{3}.\sqrt[7]{6^6}$
