Answer:
Step-by-step explanation:
64a³ - 27b³ - 144a²b + 108ab²
Here, using the identity -
(a - b)³ = a³ - b³ - 3a²b + 3ab²
⇒ 64a³ - 27b³ - 144a²b + 108ab² = (4a)³ - (3b)³ - 3(4a)²*(3b) + 3(4a)*(3b)²
⇒ (4a - 3b)³
⇒ (4a - 3b)*(4a - 3b)*(4a - 3b)

Factorise the equation :-
Let's start with simplifying the given equation :-
Now, by seeing and observing this new formed equation, we can say that the identity :-
Has been used here
Where, a will be = 4a
And, b will be = 3b
So, by all this, we can easily write that :-
= =
There's your answer. Its the final result.
