Simplify the expression using the order of operations.

Question

3×4^2–9×2
= 3×–9×2
= 3××2
= ×2
=

Answer 1

To simplify the expression \(3 \times 4^2 - 9 \times 2\), we will adhere to the order of operations (PEMDAS/BODMAS).

1. Calculate the exponent: \(4^2 = 16\)
2. Multiply:
   • \(3 \times 16 = 48\)
   • \(9 \times 2 = 18\)
3. Subtract:
   • \(48 - 18 = 30\)

Thus, the simplified expression is:

\[ 30 \]
