Answer:
(3x + 2)³ = 27x³ + 8 + 54x²+36x
Step-by-step explanation:
Formula: (a + b)³ = a³ + 3a²b + 3ab² + b³
(3x+2)³
= (3x)³ + 3(3x)²(2) + 3(3x) (2)² + (2)³
= 27x³ + 6 (9x²) + 9x (4) + 8
= 27x³ + 54x² + 36x + 8
(3x+2)³ = 27x³+8+54x²+36x

Answer:
9x³ + 54x² + 44
Step-by-step explanation:
Let 3x be 'a' and 2 be 'b'
from the formula (a + b)³ = a³ + b³ + 3ab(a + b)
Therefore, (3x + 2)³ = (3x)³ + 2³ + 3 (3x) (2) (3x + 2)
=> 9x³ + 8 + 18x (3x + 2)
=> 9x³ + 8 + 54x² + 36
=> 9x³ + 54x² + 44
