Answer 1

Ответ:

1) 5

2) 4

3) 4

4) 3 5/16

5) 7 6/25

6) 7 2/9

1) (2 1/3)^2 - 4/9 = 5

1) 2 1/3 × 2 1/3 = 5 4/9

2) 5 4/9 - 4/9 = 5

2) (1 1/2)^3 + 5/8 = 4

1) 1 1/2 × 1 1/2 × 1 1/2 = 3 3/8

2) 3 3/8 + 5/8 = 4

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

1) 2/3 × 2/3 = 4/9

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

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

1) 1/2 × 1/2 × 1/2 × 1/2 = 1/16

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

5) 7 2/5 - (2/5)^2 = 7 6/25

1) 2/5 × 2/5 = 4/25

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

6) 9 - (1 1/3)^2 = 7 2/9

1) 1 1/3 × 1 1/3 = 1 7/9

2) 9 - 1 7/9 = 7 2/9
