Explicação passo-a-passo:

a) 3 + {7 + [5 + (6 + 9 ÷ 3)]}

3 + {7 + [5 + (6 + 3)]}

3 + {7 + [5 + 9]}

3 + {7 + 14}

3 + 21

b) 2 × {18 + [3 + (32 ÷ 4 - 6)] - 10}

2 × {18 + [3 + (8 - 6)] - 10}

2 × {18 + [3 + 2] - 10}

2 × {18 + 5 - 10}

2 × 13

26

c) 25 - {4 + [1 + (14 ÷ 7 + 6 × 2)] + 1}

25 - {4 + [1 + (2 + 12)] + 1}

25 - {4 + [1 + 14] + 1}

25 - {4 + 15 + 1}

25 - 20

d) 52 + [12 ÷ (6 × 3 - 4) + 9]

52 + [12 ÷ (18 - 4) + 9]

52 + [12 ÷ 14 + 9]

52 + [ 12/14 + 9]

52 + 69/7

433/7
