Вычисли значение выражения:
​

2 1/2^2 = 5/2 * 5/2 = 25/4 = 6 1/4.

2 1/4^2 = 9/4 * 9/4 =81/16 = 5 1/16

2 2/3^2 = 8/3 * 8/3 = 64/9 = 7 1/9

2 1/5^2 = 11/5 * 11/5 = 121/25 = 4 21/25

6 1/4 : 5 1/16 =  25/4 : 81/16 = 100/81 = 1 19/81

1 19/81 : 7 1/9 = 100/81 : 64/9 = 144/25 = 5 19/25

5 19/25 : 4 21/25 = 144/25 : 121/25 = 144/121 = 1 23/121
