Resolva as seguintes expressões numéricas a) ([52 + (32 + 2?). 2] + 3 - 1) + 2? + 3 b)(2+42 +(2-5-3) - [3 + 22. (17 + 2)] + 5) + 71​

Answer 1

Explicação passo-a-passo:

a) {[52+(32+2)•2]+3-1} =

{[52+(34)•2]+3-1 =

{[52+64]+2=

{116+2}=

118

b) {2+42+(2-5-3)-[3+22•(17+2)]+5}+71 =

{2+42-6-[3+22•19]+5}+71 =

{2+42-6-[3+418]+5}+71=

{2+42-6-[421]+5}+71=

{2+42-6-421+5}+71=

{44-427+5}+71=

{-383+5}+71=

-378+71=
