(3x+2)^4 solve using pascal’s triangle

16 + 96x +216x² + 216x³ + 81x^4

Step-by-step explanation:

(3x+2)^4

4C0 * 2^4 + (3x)^0 = 1 * 16 * 1

4C1 * 2^3 * (3x)^1 = 4 * 8 * 3x

4C2 * 2^2 * (3x)^2 = 6 * 4 * 9x²

4C3 * 2^1 * (3x)^3 = 4 * 2 * 27x³

4C4 * 2^0 * (3x)^4 = 1 * 1 * 81x^4

16 + 96x +216x² + 216x³ + 81x^4
