Question

Calcule o valor destas expressões:
a) (37 – 7) : 15
b) 3 . (28 – 19) + 56 : (10 – 2)
c) [100 : (4 . 8 – 27)] : (6 . 7 – 38)
d) {11 . [15 : (7 – 4)]}​

Answer 1

Resposta:

Explicação passo a passo:

a) (37 – 7) : 15 = 30:15 = 2

b) 3 . (28 – 19) + 56 : (10 – 2) = 3 * 9 + 56 : 8  = 27 + 7 = 34

c) [100 : (4 . 8 – 27)] : (6 . 7 – 38) =  [100 : (32–27)] : (42–38) = [100 : 5] : 4 = 20 : 4 = 5

d) {11 . [15 : (7 – 4)]}​ =  {11 . [15 : 3]}​ = 11 * 12 = 132
