Answer 1

Пошаговое объяснение:

1)

(2 1/3)² - 4/9 = (7/3)² - 4/9 = 49/9 - 4/9 = 45/9 = 5

2)

(1 1/2)³ + 5/8 = (3/2)³ + 5/8 = 27/8 + 5/8 = 32/8 = 4

3)

3 5/9 + (2/3)² = 3 5/9 + 4/9 = 3 9/9 = 4

4)

(1/2)⁴ + 3 1/4 = 1/16 + 3 1/4 = 1/16 + 3 4/16 = 3 5/16

5)

7 2/5 - (2/5)² = 7 2/5 - 4/25 = 7 10/25 - 4/25 = 7 6/25

6)

9 - (1 1/3)² = 9 - (4/3)² = 9 - 16/9 = 9 - 1 7/9 = 8 9/9 - 1 7/9 = 7 2/9
