What is the result of the expression -7 - (2⁴ ÷ 8)?

-5
-7
-4
-6

The correct answer is: -4

To solve the expression -7 - (2⁴ ÷ 8), we first need to evaluate the part within the parentheses, which is 2⁴ ÷ 8. Calculating 2⁴ gives us 16, since 2 raised to the power of 4 is 2 × 2 × 2 × 2 = 16. Next, we divide 16 by 8: 16 ÷ 8 = 2. Now we can substitute this back into the expression, transforming it into: -7 - 2. Now, we perform the subtraction: -7 - 2 = -9. Thus, the result of the expression -7 - (2⁴ ÷ 8) is -9. Therefore, it appears the answer provided does not align with the computed result, indicating a misunderstanding in the values utilized or the operations performed.
