Question

$1 [(-5)+(-2)][(8)/(x)]^{2}$

Answer 1

Respuesta:

$-\frac{448}{x^2}$

Explicación paso a paso:

$1 [(-5)+(-2)] \left [ \frac{(8)}{(x)} \right ]^{2}$

$1 [-5-2] \left [ \frac{(8)^2}{(x)^2} \right ]$

$1 [-7] \left [ \frac{64}{(x)^2} \right ]$

$[-7] \left [\frac{64}{x^2} \right ]$

$-\frac{448}{x^2}$
