Answer 2

Resposta:

Explicação passo a passo:

A )

[(18+3.2) :8+5.3] :6

[(18+6):8+5.3]:6

[24:8+15]:6

[3+15]:6

18:6=3

B)

[(8•4+3):7+(3+15:5)•3]•2-9(19-7):6}•2+12

{[(32+3):7+(3+3)•3]•2-9•12:6}•2+12

{[35:7+6•3]•2-9•12:6}•2+12

{[5+18]•2-108:6}•2+12

{23•2-18}•2+12

{46-18}•2+12

28•2+12

56+12
