simplifique os racionais
$\sqrt[3]{81?}$
$\sqrt{?50}$
$\sqrt[3]{?216}$
$\sqrt[4]{?625}$
$\sqrt{625}$
$\ \sqrt[5]{?512}$
$\sqrt[5]{?32}$
$\sqrt[3]{?729}$

​

Answer 1

Simplificando:

$\sqrt[3]{81} = \sqrt[3]{27.3} = 3\sqrt[3]{3} \\\sqrt{50}=\sqrt{2.25}=5\sqrt{2}\\\sqrt[3]{216} =\sqrt[3]{6^3}= 6\\\sqrt[4]{625} =\sqrt[4]{5^4}= 5\\\sqrt{625} =\sqrt{25^2} =25\\\sqrt[5]{512} = \sqrt[5]{2^3.2^5}=2\sqrt[5]{8}\\\sqrt[5]{32} =\sqrt[5]{2^5} =5\\\sqrt[3]{729} =\sqrt[3]{9^3} =9$

Espero ter ajudado!
