Answer 1

Olá, boa noite! ☺

Bem, vamos lá ...

Prezado amigo (a), com base no enunciado acima, podemos compreender que:

$\displaystyle \mathsf {3-[4+(9^2-5)\cdot(-2)]+1}$

$\displaystyle \mathsf {3-(4+(81-5)\cdot -2)+1}$

$\displaystyle \mathsf {3-(4+76\cdot -2) +1}$

$\displaystyle \mathsf {3-(4-152)+1}$

$\displaystyle \mathsf {3+148+1}$

$\displaystyle \mathsf {3+149}$

$\boxed {\displaystyle \mathsf {152}}$
