A student correctly evaluated an expression with P = -2 and a = 3 and got 3 as the result. Which of the following expressions could she have been evaluating

B

Step-by-step explanation:

A student correctly evaluated an expression where p = -2 and q = 3 and acquired 3 as the result.

And we want to determine which expression could the student have been evaluating.

Thus, we simply need to check each expression by letting p = -2 and q = 3 and see which one equals 3.

Checking the first one:

The result is not 3. Hence, A is not correct.

The second expression:

Therefore, we can conclude that our answer is B.

We can check the other two regardless.

The third expression:

And the fourth:

Thus, neither the third expression nor the fourth is also correct.

In conclusion, our answer is B.
