Пошаговое объяснение:
1) 16 * 25= 10 * 25 + 6 * 25= 250 + 150= 400
2) 25 * 8 * 5 = 25 * 40= 1000
3) 15 * 12= 15 * 10 + 15 * 2= 150 + 30 = 180
4) 375 * 24 = 375 * 20 + 375 *4= 7500 + 1500= 9000
16 * 25 = 25 * (10 + 6) =
250 + 150 = 400
25 * 8 * 5 = (25 * 8) * 5 =
200 * 5 = 1000
15 * 12 = 15 * (10 + 2) =
150 + 30 = 180
375 * 24 = 375 * (10 + 14) = 3750 + 5250 = 9000
