Question

Determine o valor da expressão:
{[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 – (19 – 7) ÷ 6} · 2 + 12

Answer 1

Explicação passo-a-passo:

{[(8×4+3)÷7+(3+15÷5)×3]×2-(19-7)÷6}×2+12

{[(32+3)÷7+(3+15÷5)×3]×2-(19-7)÷6}×2+12

{[35÷7+(3+15÷5)×3]×2-(19-7)÷6}×2+12

{[35÷7+(3+3)×3]×2-(19-7)÷6}×2+12

{[35÷7+6×3]×2-(19-7)÷6}×2+12

{[35÷7+6×3]×2-12÷6}×2+12

{[5+6×3]×2-12÷6}×2+12

{[5+18]×2-12÷6}×2+12

{23×2-12÷6}×2+12

{46-12÷6}×2+12

{46-2}×2+12

44×2+12

88+12
