Question

alguien me resuelve esto por favor

Answer 1

$-15\left(-7+12\right)\left(-12+8.2\right)-\left(5-11\right)\left(-3\right)$
$15\left(-7+12\right)\left(-12+8.2\right)=-285$
$\left(5-11\right)\cdot \:3=-18$
$=-\left(-285\right)-18$
$=267$

$\sqrt{162}\sqrt{2}+\left(-5\right)^2+\frac{\left(-\frac{4^2}{2}-1\right)^3}{3^2}$
$\sqrt{162}\sqrt{2}=18$
$\left(-5\right)^2=5^2$
$\frac{\left(-\frac{4^2}{2}-1\right)^3}{3^2}=-3^4$
$=18+5^2-3^4$
$=-38$
