Sure, let's solve this step by step.
We want to evaluate the expression [tex]\(7 + 2 \times 9^2\)[/tex].
1. Evaluate the exponentiation first (order of operations, i.e. PEMDAS/BODMAS):
[tex]\[
9^2 = 81
\][/tex]
2. Next, perform the multiplication:
[tex]\[
2 \times 81 = 162
\][/tex]
3. Finally, perform the addition:
[tex]\[
7 + 162 = 169
\][/tex]
Hence, [tex]\(7 + 2 \times 9^2\)[/tex] evaluates to 169.
The correct answer is:
B. 169
