???108

To simplify the given expression, follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Step 1: Evaluate the expression inside the parentheses.
Inside the parentheses, we have (15 - 3)^2, which simplifies to 12^2.

Step 2: Evaluate the exponent.
12^2 means 12 raised to the power of 2, which is 12 × 12 = 144.

Step 3: Divide by 4.
We divide 144 by 4, which gives us 144 / 4 = 36.

So, the simplified expression is 3 × 36.

Step 4: Multiply.
3 × 36 = 108.

Therefore, the simplification of the expression is 108.

Answer: b. 108
