Question

{[(9/7-3/10)+9/7]÷-1/10}³ porfa me ayudan​

Answer 1

Respuesta:

$-\frac{15900}{7}$

Explicación paso a paso:

$\frac{\left(\frac{9}{7}-\frac{3}{10}\right)+\frac{9}{7}}{-\frac{1}{10^3}}$

$\frac{\frac{9}{7}-\frac{3}{10}+\frac{9}{7}}{-\frac{1}{10^3}}$

$\frac{2\cdot \frac{9}{7}-\frac{3}{10}}{-\frac{1}{10^3}}$

$-\frac{2\cdot \frac{9}{7}-\frac{3}{10}}{\frac{1}{10^3}}$

$-\frac{\left(2\cdot \frac{9}{7}-\frac{3}{10}\right)\cdot \:10^3}{1}$

$-\frac{10^3\left(\frac{18}{7}-\frac{3}{10}\right)}{1}$

$-\frac{10^3\cdot \frac{159}{70}}{1}$

$-\frac{159}{70}\cdot \:10^3$

$-\frac{159\cdot \:10^3}{70}$

$-\frac{2^2\cdot \:5^2\cdot \:159}{7}$

$-\frac{15900}{7}$
