Question

Calcule o valor de cada expressão numérica: a) [(18 + 3 · 2) ÷ 8 + 5 · 3] ÷ 6 b) {[(8 · 4 + 3) ÷ 7 + (3 + 15 ÷ 5) · 3] · 2 + (19 – 7) ÷ 6} c) 37 + [25 – (2+ 19 – 4)] = d) [2 + (22 + 5 · 6)] ÷ (5 + 2) + 2 = *

Answer 1

Resposta:

A) [(18 + 3 • 2) ÷ 8 + 5 • 3]

[(18 + 6) ÷ 8 + 5 • 3]

[24 ÷ 8 + 5 • 3]

[3 + 5 • 3]

[3 + 15]

18

B) {[(8 • 4 + 3) ÷ 7 + (3 + 15 ÷ 5) • 3] • 2 + (19 - 7) ÷ 6}

{[(8 • 4 + 3) ÷ 7 + (3 + 3) • 3] • 2 + (19 - 7) ÷ 6}

{[(32 + 3) ÷ 7 + (3 + 3) • 3] • 2 + (19 - 7) ÷ 6}

{[35 ÷ 7 + (3 + 3) • 3] • 2 + (19 - 7) ÷ 6}

{[35 ÷ 7 + 6 • 3] • 2 + (19 - 7) ÷ 6}

{[35 ÷ 7 + 6 • 3] • 2 + 12 ÷ 6}

{[5 + 6 • 3] • 2 + 12 ÷ 6}

{[5 + 18] • 2 + 12 ÷ 6}

{23 • 2 + 12 ÷ 6}

{23 • 2 + 2}

{46 + 2}

48

C) 37 + [25 - (2 + 19 - 4)]

37 + [25 - (21 - 4)]

37 + [25 - 17]

37 + 8

45

D) [2 + (22 + 5 • 6)] ÷ (5 + 2) + 2

[2 + (22 + 30)] ÷ (5 + 2) + 2

[2 + 52] ÷ (5 + 2) + 2

[2 + 52] ÷ 7 + 2

54 ÷ 7 + 2

7 + 2

9
