Приводим дроби к общему знаменателю. Степени переменных записаны верхними индексами.

5/x + 2/x² = 5x/x² + 2/x² = (5x + 2)/x².
8/a³ − 3/a = 8/a³ − 3a²/a³ = (8 − 3a²)/a³.
5/x³ + a/x² = 5/x³ + ax/x³ = (5 + ax)/x³.
1/b⁵ + c/b³ = 1/b⁵ + cb²/b⁵ = (1 + cb²)/b⁵.
4/(3a) + 5/a² = 4a/(3a²) + 15/(3a²) = (4a + 15)/(3a²).
x/(8c²) − 5/(12c) = 3x/(24c²) − 10c/(24c²) = (3x − 10c)/(24c²).
9/(10b²) − 8/(2b³) = 9b/(10b³) − 40/(10b³) = (9b − 40)/(10b³).
a/(16n²) + b/(24n³) = 3an/(48n³) + 2b/(48n³) = (3an + 2b)/(48n³).
y/(12c⁴) + x/(18c⁶) = 3yc²/(36c⁶) + 2x/(36c⁶) = (3yc² + 2x)/(36c⁶).
5/(ab⁷) − 3/(cb⁵) = 5c/(acb⁷) − 3ab²/(acb⁷) = (5c − 3ab²)/(acb⁷).
