Answer:
(k + 4)³ = k³ + 12k² + 48k + 64
Step-by-step explanation:
Expansion of the algebraic identity (a + b)³ is:
[tex](a +b)^{3} = a^{3} + b^{3} + 3a^{2} b+3ab^{2}[/tex]
Step 1:a = k
b = 4
(a + b)³ = (k + 4)³
Step 2:Expanding using the identity:
(k + 4)³ = k³ + 4³ + 3k²×4 + 3k×4²
(k + 4)³ = k³ + 64 + 12k² + 48k
(k + 4)³ = k³ + 12k² + 48k + 64
