(5a - 2)^3 = (5a - 2)(5a - 2)(5a - 2)Expanding this expression, we get:
= (25a^2 - 10a - 10a + 4)(5a - 2)= (25a^2 - 20a + 4)(5a - 2)= 125a^3 - 100a^2 + 20a^2 - 16a= 125a^3 - 80a^2 - 16a
Therefore, (5a - 2)^3 = 125a^3 - 80a^2 - 16a.
(5a - 2)^3 = (5a - 2)(5a - 2)(5a - 2)
Expanding this expression, we get:
= (25a^2 - 10a - 10a + 4)(5a - 2)
= (25a^2 - 20a + 4)(5a - 2)
= 125a^3 - 100a^2 + 20a^2 - 16a
= 125a^3 - 80a^2 - 16a
Therefore, (5a - 2)^3 = 125a^3 - 80a^2 - 16a.
