Question

como se ace las expreciones​

Answer 1

Respuesta:

A.

$\sqrt[3]{-8}+\left(-1\right)^{\frac{2}{3}}\\\\=-2+\left(-1\right)^{\frac{2}{3}}\\\\=-2+1\\\\=-1$

B.

$\frac{-4^{\frac{1}{2}}-\sqrt[3]{-27}}{\sqrt{121}}\\\\=\frac{-4^{\frac{1}{2}}+27^{\frac{1}{3}}}{\sqrt{121}}\\\\=\frac{-4^{\frac{1}{2}}+27^{\frac{1}{3}}}{11}\\\\=\frac{-2+3}{11}\\\\=\frac{1}{11}$

C.

$\frac{\sqrt{100-\sqrt{4}}}{\sqrt[18]{0}}\\\\=\frac{\sqrt{100-\sqrt{4}}}{0}$

no esta definida así que termina ahí

= sin definir

D.

$-64^{\frac{1}{3}}\sqrt{100}\\\\=-64^{\frac{1}{3}}\cdot \:10\\\\=-4\cdot \:10\\\\=-40$
