Answer:
37. 18
38. 3
39. 115
40. 60
Step-by-step explanation:
37. = 2 + (7 x 3) - 5
= 2 + (21) - 5
= 2 + 21 - 5
= 23 - 5
= 18
38. = 3 x 4 ÷ (7-5) - 12 ÷ 4
= 3 x 4 ÷ (2) - 12 ÷ 4
= 12 ÷ 2 - 12 ÷ 4
= 6 - 3
= 3
39. = (10⁴ + 1500) ÷ 100
= (10,000 + 1500) ÷ 100
= ( 11,500) ÷ 100
= 115
40. = 42 - 4 x 3² + 2 (5-2)³
= 42 - 4 x 3² + 2 (3)³
= 42 - 4 x 3² + 2 (27)
= 42 - 4 x 9 + 2 (27)
= 42 - 36 + 2 ( 27)
= 42 - 36 + 2 x 27
= 42 - 36 + 54
= 6 + 54
= 60
