Question

expand (3a+1/4b)^3 solve it guys!!!!

Answer 1

(3a + 1/4b)^3

Apply (a + b)^3 = a^3 + b^3 + 3a^2b + 3ab^2

= (3a)^3 + (1/4b)^3 + 3 (3a)^2(1/4b) + 3 (3a) (1/4b)^2

= 27a^3 + 1/64b^3 + 27/4a^2b + 9/16ab^2


Thanks

Answer 2

Hey buddy!
Here is your answer....

APPLY THE FORMULA
(a+b)³ = a³+b³ + 3a²b + 3ab²

QUESTION :- (3a+1/4b)³

➡️(3a)³+ (1/4)³+ 3(3a)²(1/4) + 3(3a)(1/4b)²

➡️27a³+ 1/64b³+27/4a²b + 9/16ab²

Hope it helps u sis!!!
