Question

realiza las operaciones propuestas
$a)( \frac{2}{5} ) {}^{3} .( \frac{2}{5} ) {}^{2}$
$b)( \frac{2}{3} ) {}^{3} \div ( \frac{2}{3} ) {}^{ - 2}$
$c)( \frac{2}{5} ) {}^{3} .( \frac{5}{2} ) {}^{2}$
​

Answer 1

Respuesta:

$a)(\frac{2}{5})^{3}*(\frac{2}{5})^{2}=( \frac{8}{125})*(\frac{4}{25})=\frac{32}{3125}\\\\b)(\frac{2}{3})^{3}/(\frac{2}{3})^{-2}=(\frac{8}{27})/(\frac{9}{4})=\frac{2}{3}\\\\c)(\frac{2}{5})^{3}*(\frac{5}{2})^{2}= (\frac{8}{125})*(\frac{25}{4})=\frac{200}{100}=2$
