Question

Вычислите удобным способом:
1)25*14*6
2)125*25*32
3)75*36
4)96*50

Помогите,пожалуйста.

Answer 1

25 * 14 * 6 = 25 * (7 * 2) * (2 * 3) = (25 * 2 * 2) * (7 * 3) = (25 * 4) * 21 =

= 100 * 21 = 2100

125 * 25 * 32 = 125 * 25 * (4 * 8) = (125 * 8) * (25 * 4) = 1000 * 100 =

= 100 000

75 * 36 = (3 * 25) * (4 * 9) = (25 * 4) * (3 * 9) = 100 * 27 = 2700

96 * 50 = (48 * 2) * 50 = (50 * 2) * 48 = 100 * 48 = 4800
