Question

a) 4x { 2 x [4 x 9-(9:3-2)]: 5} =

b) 4x { 19 + [5+ ( 32 : 4 - 6) + ( 36 : 9 + 12:4)] - 10 ) = ​

Answer 1

Resposta:

a) 4x {2x [4x9-(9:3-2)]:5}=

4x {2x[4x9-1]:5}=

4x{2x 35 : 5}=

4x  14 =

56

b) 4x {19 + [5+ (32 : 4 - 6) + (36 : 9 = 12:4)] -10) =

4x { 19 + [ 5 + 0 + 4 + 3 - 10] =

4x { 19 +2 =

4x 21=

84
