Answer 1

Let's simplify the expression step by step, following the order of operations.

1. Start with the original expression: \( 3 \times 4^2 - 9 \times 2 \).

2. Evaluate the exponent: \( 4^2 = 16 \). So, the expression becomes: \( 3 \times 16 - 9 \times 2 \).

3. Perform the multiplications:

   • \( 3 \times 16 = 48 \)
   • \( 9 \times 2 = 18 \)

   Now, we have: \( 48 - 18 \).

4. Finally, subtract: \( 48 - 18 = 30 \).

So the final simplified result is: \[ \boxed{30} \]
