Answer :

Answer:

x³ + 9x² + 27x + 27

Step-by-step explanation:

(x + 3)³ = (x + 3) (x + 3) (x + 3)

Using the distributive property and multiplying the terms:

(x + 3) (x + 3) (x + 3)

= (x² + 6x + 9) (x + 3)

= x³ + 6x² + 9x + 3x² + 18x + 27

= x³ + 9x² + 27x + 27

So, the answer is x³ + 9x² + 27x + 27 .
