Question

alguem me ajuda pfvv​

Answer 1

Resposta:

Explicação passo a passo:

$a)$

$(\sqrt{17}) ^{2} =\sqrt{17^{2} } =17$

$b)$

$(\sqrt[3]{2}) ^{4} =\sqrt[3]{2^{4} } =\sqrt[3]{2^{3}.2 } =2\sqrt[3]{2}$

$c)$

$(6\sqrt{2}) ^{2} =6^{2}\:.\:(\sqrt{2}) ^{2} =36\:.\:2=72$

$d)$

$(\frac{1}{2}\sqrt{10}) ^{2} =(\frac{1}{2}) ^{2} \:.\:(\sqrt{10}) ^{2} =\frac{1}{4}\:.\:10=\frac{10}{4}=\frac{5}{2}$
