Question

boa noite! Gostaria de uma ajuda nesses cálculos.

Grata, Tatianaa

100-[5²:(10-5)+2³]   

   [4²+(5-3)³]:(9-7)³

Answer 1

100-[25:5+8] => 100-[5+8] =>100-13=>97

[16+(2)³]:(2)³=> [16+8]:8=>24:8=>3

Answer 2

$a)100-[5 ^{2}:(10-5)+2 ^{3}]=\\100-[5 ^{2}:5+2 ^{3}]=\\100-13=87$

$b)[4 ^{2}+(5-3) ^{3}]:(9-7) ^{3}=\\(4 ^{2}+8):8=\\24:8=3$
