Answer 1

Resposta:

$a)\sqrt{18} =\sqrt{2*3^2} =\sqrt{2} *\sqrt{3^2} =\sqrt{2} *3=3\sqrt{2\\\\} \\\\\\\\\\b)\sqrt{27} =\sqrt{3^3} =\sqrt{3^2*3} =\sqrt{3^2} *\sqrt{3} =3\sqrt{2} \\\\\\\\\\c)\sqrt[3]{81} =\sqrt[3]{3^4} =\sqrt[3]{3^3*3} =\sqrt[3]{3^3} *\sqrt[3]{3} =3\sqrt[3]{3} \\\\\\\\\\d)\sqrt[3]{72} =\sqrt[3]{2^3*3^2} =\sqrt[3]{2^3} *\sqrt[3]{3^2} =2\sqrt[3]{3^2} =2\sqrt[2]{9} \\\\\\\\\\e)\sqrt[4]{32} =\sqrt[4]{2^5} =\sqrt[4]{2^4*2} =\sqrt[4]{2^4} *\sqrt[4]{2} =2\sqrt[4]{2}$

$f)\sqrt[5]{64} =\sqrt[5]{2^6} =\sqrt[5]{2^5} *\sqrt[5]{2} =2\sqrt[5]{2}$
