Question

Aplique as propriedades da raiz de um produto e calcule!

Answer 1

Resposta:

$a)\\ \sqrt{36~.~25} =\sqrt{36} ~. ~\sqrt{25} =6~.~5=30\\ \\ b)\\ \sqrt[3]{27~.~8} =\sqrt[3]{27} ~.\sqrt[~3]{8} =\sqrt[3]{3^3} ~.\sqrt[~3]{2^3} =3~.~2=6$

$c)\\ \sqrt[4]{2^8} ~.\sqrt[~4]{4^2} =\sqrt[4]{2^4.2^4} ~.\sqrt[~4]{2^4} =2.2.2=8\\ \\ d)\\ \sqrt{3~.~12} =\sqrt{36} =6\\ \\ ou\\ \\ \sqrt{3} ~.\sqrt{~12} =\sqrt{3} ~.\sqrt{~2^2.3} =\sqrt{3} ~.~2\sqrt{3} =2\sqrt{9} =2~.~3=6$
