Answer 1

Resposta:

Vamos lá!

$(\sqrt{7} )^{3} =7\sqrt{7} \\\\(3\sqrt{5} )^{2} =9.5=45\\\\(\sqrt{\dfrac{3}{4} } )^{3} =\dfrac{3}{4} \sqrt{\dfrac{3}{4} }\\\\\\(\sqrt[4]{9} )^{2} =\sqrt{9} =3\\\\(2\sqrt[5]{27} )^{4} =16(\sqrt[5]{3^{5} .3^{5}.9 } )=16.9\sqrt[5]{9} =144\sqrt[5]{9}\\\\\\(3\sqrt{2a+1} )^{2} =9.(2a+1)=18a+9$
