Answer 2

b) 9

4² – 10 + (2³ – 5) =

4² – 10 + (8 – 5) =

4² – 10 + 3 =

16 – 10 + 3 =

6 + 3 =

9

c) 29

30 – (2 + 1)² + 2³ =

30 – 3² + 2³ =

30 – 9 + 2³ =

30 – 9 + 8 =

21 + 8 =

29

d) 17

20 – [6 – 4 × (10 – 3²) + 1] =

20 – [6 – 4 × (10 – 9) + 1] =

20 – [6 – 4 × 1 + 1] =

20 – [6 – 4 + 1] =

20 – [2 + 1] =

20 – 3 =

17

e) 62

25 + {3³ ÷ 9 + [3² × 5 − 3 × (2³ − 5)]} =

25 + {3³ ÷ 9 + [3² × 5 − 3 × (8 − 5)]} =

25 + {3³ ÷ 9 + [3² × 5 − 3 × 3]} =

25 + {3³ ÷ 9 + [9 × 5 − 3 × 3]} =

25 + {3³ ÷ 9 + [45 − 3 × 3]} =

25 + {3³ ÷ 9 + [45 − 9]} =

25 + {3³ ÷ 9 + 36} =

25 + {9 ÷ 9 + 36} =

25 + {1 + 36} =

25 + 37 =

62

f) 76

(8 ÷ 2) × 4 + {[(3² − 2³) × 2⁴ − 5⁰] × 4¹} =

(8 ÷ 2) × 4 + {[(9 − 2³) × 2⁴ − 5⁰] × 4¹} =

(8 ÷ 2) × 4 + {[(9 − 8) × 2⁴ − 5⁰] × 4¹} =

4 × 4 + {[(9 − 8) × 2⁴ − 5⁰] × 4¹} =

4 × 4 + {[1 × 2⁴ − 5⁰] × 4¹} =
