Объяснение:

Используем формулу :

(а + в)³ = а³ + 3а²в + 3ав² + в³

(а + 2х)³ = а³ + 6а²х + 12ах² + 8х³

(4n - 3m)³ = 64n³ - 144mn² + 108m²n - 27m³

(-c - 3k)³ = -c³ - 9c²k - 27ck² - 27k³

(3y + b)³ = 27y³ + 27by² + 9b²y + b³

(2a - 5x)³ = 8a³ - 60a²x + 150ax² - 125x³

(-2 - m)³ = -m³ - 6m² - 12m - 8
