Question

Me ajudem por favor eu não consigo entender

Answer 1

Resposta:

$3) \sqrt[3]{\frac{a}{b} \sqrt{\frac{a}{b} } } \\\\\sqrt[3]{\frac{a}{b}\frac{\sqrt{a} }{\sqrt{b}} } \\\sqrt[3]{\sqrt{\frac{a.a}{b.b} } } \\\\\sqrt[3]{\frac{(2a)^{\frac{1}{2} } }{(2b)^{\frac{1}{2} } } } } \\(2a/2b)^{\frac{1}{2}.\frac{1}{3} } \\\sqrt[6]{\frac{2a}{2b} }$

Explicação passo-a-passo:

$4)\\\sqrt{3\sqrt{3\sqrt3} } \\\sqrt{3}(3)}^{\frac{1}{2} } (3)^{\frac{1}{2} }\\\ (3)^{\frac{1}{2} } (3)^{\frac{1}{2} } (3)^{\frac{1}{2} } \\= 3^{\frac{1}{2}.\frac{1}{2}.\frac{1}{2} } \\ = 3^{\frac{1}{8} } \\ = \sqrt[8]{3}$
