2)(8 + 2).3+ 18:9=
3) (20-5):3+ ( 2 + 1).4 =
4) (11 +5):4 + ( 25 – 15): 5+ [3.7 - (4.3+5) + 1] =
5) 15-{[( 4.5+ 7) + (8:4+ 6)]:5}=​

Answer 1

Resposta:

1)= 4     2)= 32   3)= 17 4)=11  5)=8

Explicação passo-a-passo:

1) 14 – 5 + 3–7-1 =

9+3-7-1=

12-7-1=

5-1=4

2)(8 + 2).3+ 18:9=

10. 3 + 18:9=

30  + 2=

30 +2 = 32

3) (20-5):3+ ( 2 + 1).4 =

15:3 + 3 .  4=

5 + 12= 17

4) (11 +5):4 + ( 25 – 15): 5+ [3.7 - (4.3+5) + 1] =

16:4+ 10:5 + [ 3 . 7 - (12+5) + 1]=

16:4+ 10:5 + [ 3. 7 - 17 + 1]=

16:4+ 10:5 + [ 21-17 +1]

16:4+ 10:5 + 5=

4 + 2 + 5= 11

5) 15-{[( 4.5+ 7) + (8:4+ 6)]:5}=​

15 - {[(27) + (8)]:5}=

15- {[35:5]`}=

15-7=8
