espero ter ajudado.

Answer 2

a)

$-2+\left\{-5-[-2-{(-2)}^{3}-3-{(3-2)}^{9}] </p><p>+5\right\}$

$-2+\left\{-5-[-2+8-3-1+5\right\}$

$-2+\left\{-5-[-2+8-3-1]+5\right\}$

$-2+\left\{-5-2+5\right\}$

$-2+\left\{-\cancel5-2+\cancel5\right\}$

$\color{blue}{-2-2=-4}\color{green}{\checkmark}$

b)

$18-\left\{\sqrt{36}-[-3-(5-4)-{(7-9)}^{3}] -1\right\}$

$18-\left\{\sqrt{36}-[-3-1+8]-1\right\}$

$18-\left\{6-4-1\right\}$

$\color{blue}{ 18-1=17}\color{green} {\checkmark}$
