Пошаговое объяснение:

3 * (2/3)³ - 2 * (1/2)³ - 6 * (2/3)² * (1/2)² + 2/3 * 1/2 = 11/36

1) 3 * (2/3)³ = 3 * 8/27 = 1 * 8/9 = 8/9

2) 2 * (1/2)³ = 2 * 1/8 = 2/8 = 1/4

3) 6 * (2/3)² * (1/2)² = 6 * 4/9 * 1/4 =

6 * 1/9 = 6/9 = 2/3

4) 2/3 * 1/2 = 2/6 = 1/3

5) 8/9 - 1/4 - 2/3 + 1/3 = 32/36 - 9/36 - 24/36 + 12/36 = (32-9-24+12)/36 = 11/36

Ответ: 11/36
