Resolva as expressões :

Answer 1

Resposta:

6

Explicação passo-a-passo:

j) [√100-(16-8).2-24] : [4+1]

  [√100 - 8.2-24] : [5]

  [√100 -16 -24] : 5

  [10 -40] : 5

  -30 :5 = -6

Answer 2

j) 6

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

[√100 − (16 − 8) × 2 − 24] ÷ [2² − (-3 + 2)] =

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

[√100 − 8 × 2 − 24] ÷ [2² − -1] =

[10 − 8 × 2 − 24] ÷ [2² − -1] =

[10 − 8 × 2 − 24] ÷ [4 − -1] =

[10 − 16 − 24] ÷ [4 − -1] =

[-6 − 24] ÷ [4 − -1] =

30 ÷ [4 − -1] =

30 ÷ 5 =

6

k) 40

{[(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 − (19 − 7) ÷ 6} × 2 + 12 =

{[35 ÷ 7 + (3 + 3) − 3] × 2 − (19 − 7) ÷ 6} × 2 + 12 =

{[35 ÷ 7 + 6 − 3] × 2 − (19 − 7) ÷ 6} × 2 + 12 =

{[35 ÷ 7 + 6 − 3] × 2 − 12 ÷ 6} × 2 + 12 =

{[5 + 6 − 3] × 2 − 12 ÷ 6} × 2 + 12 =

{[11 − 3] × 2 − 12 ÷ 6} × 2 + 12 =

{8 × 2 − 12 ÷ 6} × 2 + 12 =

{16 − 12 ÷ 6} × 2 + 12 =

{16 − 2} × 2 + 12 =

14 × 2 + 12 =

28 + 12 =

40
