Question

Explain, in sentence form, why −92 ≠ (−9)2. Keep in mind that you will be marked based on the words in your explanation, not the numbers.

Answer 1

The expression −92 is not equal to (−9)2 because the negative sign in front of 92 affects the entire number, while in (−9)2, only the number 9 is squared and the negative sign is not applied to the squared result.
