2^4-4

A 12

B 0

C 4

D 2

The answer is B) 0.

When we calculate 2^4, which represents 2 raised to the power of 4, we get 16.

Then we subtract 4, so 16 - 4 = 12.

Therefore, the correct answer is B) 0.

To evaluate the expression 2^4 - 4, we need to follow the order of operations rules. First, we calculate the exponentiation, and then perform the subtraction.

Step 1: Calculate the exponentiation.
2^4 = 2 * 2 * 2 * 2 = 16.

Step 2: Perform the subtraction.
16 - 4 = 12.

Therefore, the correct answer is A) 12.
