Question

Expand (a + 4)3 the following question​

Answer 1

Answer:

(a + 4)³ = a³ + 12a² + 48a + 64

Step-by-step explanation:

Expand :- (a + 4)³

.

as we know that:-

(a + b)³ = a³ + 3a²b + 3ab² + b³

.

.

so,

(a + 4)³ = (a)³ + 3(a)²•(4) + 3(a)•(4)² + (4)³

.

(a + 4)³ = a³ + 12a² + 3(a)•(16) + 64

.

(a + 4)³ = a³ + 12a² + 48a + 64 (Answer)
