Question

Choose the best answer from the options below:
A 16
B 18
C 36
D 176

Answer 1

To evaluate the expression, we must follow the order of operations.

First, we calculate the expression inside the parentheses:
(7 to the power of 2 - 15 ÷ 3) x 2 to the power of 2
= (49 - 15 ÷ 3) x 2 to the power of 2
= (49 - 5) x 2 to the power of 2
= 44 x 2 to the power of 2

Next, we calculate the exponentiation:
= 44 x 4
= 176

Therefore, the answer is D) 176.
