Question

Usando as propriedades dos radicais,como resolvo? (eu ja respondi,quero ver se estou certo :D)

Answer 1

$a)[(\sqrt[3]{x^{2}} )^{3}]^{3}=(\sqrt[3]{ x^{2}})^{9} \\ =\sqrt[3]{x} ^{18}= x^{6} \\ b)(\sqrt[3]{\sqrt{x^{5}}})^{6}=\sqrt[6]{ x^{30} }= x^{5} \\ \\c) \frac{ \sqrt[5]{ x^{8}.y^{7}.z^{9}}}{\sqrt[5]{x^{2}. y^{2}.z^{2}}} \\ = \sqrt[5]{x^{6}.y^{5}.z^{7}} \\ =x.y.z \sqrt[5]{ x.z^{2}}$
