(2a-3b)power 3
​

Answer 1

Answer:

(2a-3b)³,Expand it, using suitable identities. 2. See answers ... Now , ( 2a - 3b )³ = (2a)³-3*(2a)²*3b+3*2a*(3b)²-(3b

Answer 2

Answer:

8a³ - 36a²b + 36ab² - 27b³

Step-by-step explanation:

To find - cube of ( 2a-3b )

⇒(2a - 3b)³

[Identity use—-> (a-b)³ = a³ - 3a²b + 3ab² - b³]

⇒8a³ - 3(4a²)(3b) + 3(2a)(6b²) - 27b³

∴8a³ - 36a²b + 36ab² - 27b³ is your answer

HOPE IT HELPS YOU:)
