Answer:
Question : (2a^3 - b^2)^3 :: Answer = 8a^9 - 12a^6b^2 + 6a^3b^4 - b^6
Step-by-step explaination:
IF YOU UNDERSTAND IT WELL, PLEASE MARK AS BRAINLIEST.
By applying formula (a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3
(2a^3 - b^2)^3
a= 2a^3 b = b^2
(2a^3 - b^2)^3 = [(2a^3)^3] - [3 X (2a^3)^2 X b^2] + [3 X (2a^3) X (b^2)^2 ] - (b^2)^3
(2a^3 - b^2)^3 = 8a^9 - [3 X 4a^6 X b^2] + [3 X 2a^3 X b^4] - b^6
(2a^3 - b^2)^3 = 8a^9 - 12a^6b^2 + 6a^3b^4 - b^6
