38. Выполни вычисления.

Решение:

• \( 42 - 57 : 19 \times 14 = 42 - 3 \times 14 = 42 - 42 = 0 \)
• \( 68 : (96 - 62) \times 9 = 68 : 34 \times 9 = 2 \times 9 = 18 \)
• \( 5 \times (98 - 10 \times 8) = 5 \times (98 - 80) = 5 \times 18 = 90 \)
• \( 96 : (4 \times 18 - 56) = 96 : (72 - 56) = 96 : 16 = 6 \)
• \( 14 \times (19 \times 4 - 71) = 14 \times (76 - 71) = 14 \times 5 = 70 \)
• \( 6 \times (69 : 23 + 7) = 6 \times (3 + 7) = 6 \times 10 = 60 \)
