b) [-1 + (22–5 · 6)] ÷ (-5 + 2) + 1 =
c)[√100–(24–8) · 2 –24] ÷ [22–(-3 + 2)] =
d) {[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 –(19 –7) ÷ 6} · 2 + 12 =

Answer 1

A) (0)

Explicação passo a passo:

3-{2+(11-15)-[5+(-3+1)]+8}=

3- {2 + ( -4 ) - [ 5+ ( -3 + 1 ) ] +8}=

3- {2 + ( -4 ) - ( 5+ ( -2 ) ] +8 }=

3- {2 - 4 - ( 5+ ( -2 ) ] +8 }=

3- {2 - 4 - ( 5 - 2 ) +8 }=

3- {2 - 4 - 3 + 8 }=

3 - 3 =

0

B) (4)Explicação passo a passo:

[ -1 + ( 22 -5 × 6 ) ] ÷ ( - 5 +2 ) +1 =

[ -1 + ( 22 - 30 ) ] ÷ ( - 5 +2 ) +1 =

[ -1 + ( 22 - 30 ) ] ÷ ( -3 ) +1 =

[ -1 + ( -8 ) ] ÷ ( -3 ) +1 =[ -1 -8 ] ÷ ( -3 ) +1=

3 + 1 =

4

C) (-2)Explicação passo a passo:

[√100 - (24 - 8 ) × 2 - 24] ÷ [ 22 - ( -3 + 2 )]=

[ 10 - ( 24 -8 ) × 2 - 24] ÷ [ 22 - ( -3 +2 )]=

[ 10 - 16 × 2 - 24 ] ÷ [ 22 - (-3 +2) ]=

[ 10 - 16 × 2 - 24 ] ÷ [ 22 - ( -1 )]=

[ 10 - 32 - 24 ] ÷ [ 22 - ( -1 )]=

[ 10 - 33 - 24 ] ÷ [ 22 + 1 ]=

- 46 ÷ 23 =

-2

D) (100)

{[( 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=

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

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

{[35 ÷ 7+ (3 + 3) ×3] × 2- 12 ÷ 6} ×2 + 12=

{[35 ÷ 7+ 6 × 3] ×2 -12 ÷ 6} ×2 + 12=

{[35 ÷ 7+ 6 × 3] ×2 -2} ×2 + 12=

{[5 + 6 × 3] ×2 -2} ×2 + 12=

{[5 + 18] ×2 -2} ×2 + 12=

{23 ×2 -2} ×2 + 12=

{46 -2} ×2 +12=44 × 2 + 12=

88 + 12 =

100
