(6 1/2 - 5 1/8)^3 - (5 3/4 - 4 3/8)^2 = (13/2 - 41/8)^3 - (23/4 - 35/8)^2 = (11/8)^3 - (11/8)^2 = 1331/512 - 121/64 = 363/512

Ответ:

363/512

Пошаговое объяснение:

(6 1/2 - 5 1/8) ^3 = (13/2 - 41/8)^3 = (11/8)^3 = 1331/512

(5 3/4 - 4 3/8)^2 = (23/4 - 35/8)^2 = (11/8)^2 = 121/64

1331/512 - 121/64 = 1331-968/512 = 363/512
