Alguien que me ayude por favorr

∛0.36 × 15/22 =

∛( 3/5 - 1 ) × 5/16 =

Answer 1

$\sqrt[3]{0.36}\frac{15}{22}$
$=\frac{15\sqrt[3]{0.36}}{22}$
$=\frac{15\cdot \:0.71138\dots }{22}$
$=\frac{10.67068\dots }{22}$
$=0.48503\dots$


$\sqrt[3]{\frac{3}{5}-1}\frac{5}{16}$
$=-\sqrt[3]{\frac{2}{5}}\frac{5}{16}$
$=-\frac{5\sqrt[3]{\frac{2}{5}}}{16}$
$=-\frac{5\cdot \frac{\sqrt[3]{2}}{\sqrt[3]{5}}}{16}$
$=-\frac{\sqrt[3]{2}\cdot \:5^{\frac{2}{3}}}{16}$
$=-\frac{5^{\frac{2}{3}}}{2^{\frac{11}{3}}}$
$=-\frac{5^{\frac{2}{3}}}{2^3\cdot \:2^{\frac{2}{3}}}$
$=-\frac{5^{\frac{2}{3}}}{2^{\frac{2}{3}}\cdot \:8}$
$=-\frac{\sqrt[3]{2}\cdot \:5^{\frac{2}{3}}}{16}$
