Question

{[(8.4+3)÷7+(3+15÷5).3].2-(19-7)÷6}.2+12=
Me ajudem!!!!

Answer 1

8 x 4 = 32 
32+3= 35 
35÷7= 5 
5+ (3+15)= 23
23÷5= 4.6 
4.6x3= 13,8
13,8x2= 27,6
27,6-(19-7)= 1,6
1,6÷6= 0,2666....
0,266....x 14= 3.73324

Answer 2

{[(8.4+3)÷7+(3+15÷5).3].2-(19-7)÷6}.2+12=
{[35÷7+3,6.3].2-12÷6}.2+12=
{[35÷7+10,8].2-12÷6}.2+12
{[5+10,8].2-12÷6}.2+12
{15,8.2-12÷6}.2+12
{31,6-12÷6}.2+12
{31,6-2}.2+12
29,6.2+12
59,2+12
