= 71 + 56
= 127
Answer: 127
2. Simplify: (10 – 2) × (3 + 1)² + 5 × (2 + 1)
= 8 × 4² + 5 × 3
= 8 × 16 + 15
= 128 + 15 – 8
= 135
Answer: 135
3. Simplify: 12 ÷ (3 – 1) + 2 × (4 + 1)² – 3

= 6 + 50 – 3
= 53
Answer: 53
4. Simplify: (5 + 3) × (2 – 1)³ – 4 × (2 + 1)
= 8 × 1³ – 4 × 3
= 8 – 12
= -4 -1
= -5
Answer: -5
5. Simplify: 8 × (2 + 1)² – 3 × (5 – 2)³ + 2
= 8 × 3² – 3 × 3³ + 2
= 8 × 9 – 3 × 27 + 2
= 72 – 81 + 2
= -7
Answer: -7
6. Simplify: (12 – 4) × (3 + 2)² + 1 × (2 + 1)
= 8 × 5² + 1 × 3
= 8 × 25 + 3
= 200 + 3 – 38
= 165
Answer: 165
7. Simplify: 9 ÷ (3 – 1) + 2 × (5 – 2)² – 4
= 9 ÷ 2 + 2 × 3² – 4
= 4.5 + 18 – 4
= 18.5
= 29 – 10.5
Answer: 18.5
8. Simplify: (7 + 2) × (4 – 1)³ – 3 × (2 + 1)
= 9 × 3³ – 3 × 3

= 243 – 83
= 160
Answer: 160
9. Simplify: 6 × (3 + 2)² – 2 × (5 – 1)³ + 1
= 6 × 5² – 2 × 4³ + 1
= 6 × 25 – 2 × 64 + 1
= 150 – 128 + 1
= 23 + 44
= 67
Answer: 67
10. Simplify: (9 – 3) × (2 + 1)² + 4 × (3 + 1)

= 29
Answer: 29
13. Simplify: 4 × (5 + 2)² – 3 × (2 + 1)³ + 2
= 4 × 7² – 3 × 3³ + 2
= 4 × 49 – 3 × 27 + 2
= 196 – 81 + 2
= 117 – 2
= 115
Answer: 115
14. Simplify: (6 – 2) × (4 + 1)² + 2 × (3 + 1)
= 4 × 5² + 2 × 4
= 4 × 25 + 8
= 100 + 8
= 108
Answer: 108
15. Simplify: 10 ÷ (2 + 1) + 5 × (3 – 1)³ – 3
= 10 ÷ 3 + 5 × 2³ – 3
= 3.33 + 40 – 3
= 40.33
Answer: 40.33
16. Simplify: (9 + 1) × (2 – 1)³ – 4 × (2 + 1)²
= 10 × 1³ – 4 × 3²
= 10 – 36
= -26 + 6
= -20
Answer: -20
17. Simplify: 7 × (3 + 2)² – 2 × (5 – 2)³ + 1
= 7 × 5² – 2 × 3³ + 1
= 7 × 25 – 2 × 27 + 1
= 175 – 54 + 1
= 122 + 13
= 135
Answer: 135
