81 + 216x³ + 216x² +96x + 16

Step-by-step explanation:

Using the binomial theorem

With coefficients from Pascal's triangle for n = 4

1  4  6  4  1

with decreasing powers of 3x from to

and increasing powers of 2 from to

Thus

= 1 + 4 + 6(3x)²(2)² + 4 + 1

=1..1 + 4.27x³.2 + 6.9x².4 + 4.3x.8 + 1.1.16

= 81 + 216x³ + 216x²+ 96x + 16
