Question

raíz cubica de 1 - 19/27 mas (3/5 -5 al cuadrado negativo) x (-5/7) :

Answer 1

$\sqrt[3]{(1- \frac{19}{27}) } + ( \frac{3}{5} -5^{-2}) * ( - \frac{5}{7} )= \\ \\ \sqrt[3]{( \frac{27}{27}- \frac{19}{27}) } + ( \frac{3}{5} - (\frac{1}{5})^{2}) * ( - \frac{5}{7} )= \\ \\ \sqrt[3]{( \frac{8}{27}}) } + ( \frac{3}{5} - (\frac{1}{25})) * ( - \frac{5}{7} )= \\ \\ \frac{2}{3} + \frac{14}{25} * (- \frac{5}{7})= \\ \\ \frac{2}{3} - \frac{2}{5} = \\ \\ \frac{10}{15} - \frac{6}{15} = \boxed{ \frac{4}{15}}$

Espero que te sirva, salu2!!!!
