Exponents with a Negative Base:

A number is even if the final digit is divisible by 2:

• 0, 2, 4, 6, or 8

A number is odd if the final digit is not divisible by 2:

• 1, 3, 5, 7, or 9

When the exponent is odd, the answer is always negative

When the exponent is even:

- The answer is positive if the negative is wrapped inside of parentheses
- The answer is negative if the negative is not wrapped inside of parentheses
