By using pascles's triangle expand `(2x+3y)^(4)`.

Explanation

To expand \( (2x + 3y)^4 \) using Pascal's Triangle, we follow these steps:

### Step 1: Identify the Coefficients from Pascal's Triangle
Pascal's Triangle gives us the coefficients for the binomial expansion. For \( n = 4 \), we look at the 5th row of Pascal's Triangle, which is:
\[ 1, 4, 6, 4, 1 \]

### Step 2: Write the General Term
The general term in the expansion of \( (a + b)^n \) is given by:
