Question

A)
$\sqrt[3]{1 - \frac{7}{8} } =$
B)
$\sqrt[3]{ \frac{13}{8} } ^{3}$
C)
$\sqrt{5} \div \sqrt{20 } =$
​

Answer 1

Respuesta:

$A.\ =\frac{1}{2}\\ B.\ = \frac{13}{8}\\ C.\ = \frac{1}{2}$

Explicación paso a paso:

$A.\ =\sqrt[3]{\frac{1}{8}}\\ =\frac{\sqrt[3]{1}}{\sqrt[1]{8}}\\ \sqrt[3]{8}=2\\ =\frac{\sqrt[3]{1}}{2}\\ =\frac{1}{2}\\ \\B.\ =((\frac{13}{8})^{\frac{1}{3}})^{3}\\ =(\frac{13}{8})^{\frac{1}{3}(x)3}\\ \frac{1}{3}(x)3=1\\=\frac{13}{8}\\\\C. =\sqrt{50\div}\sqrt{20}=\frac{1}{4} \\ =\sqrt{\frac{1}{4}}\\ =\frac{\sqrt{1}}{\sqrt{4}}\\\sqrt{4}=2\\ =\frac{\sqrt{1}}{2}\\ =\frac{1}{2}$
