Решение:
- 65 * 3 = (60 + 5) * 3 = 60 * 3 + 5 * 3 = 180 + 15 = 195
- 93 * 4 = (90 + 3) * 4 = 90 * 4 + 3 * 4 = 360 + 12 = 372
- 78 * 2 = (70 + 8) * 2 = 70 * 2 + 8 * 2 = 140 + 16 = 156
- 316 * 3 = (300 + 10 + 6) * 3 = 300 * 3 + 10 * 3 + 6 * 3 = 900 + 30 + 18 = 948
- 185 * 5 = (100 + 80 + 5) * 5 = 100 * 5 + 80 * 5 + 5 * 5 = 500 + 400 + 25 = 925
Ответ: 195; 372; 156; 948; 925.
