1. False. If the exponent is even it is positive.
2. False. The square root of a negative number is imaginary
3. False. The additive inverse of a negative number is it's opposite.. which means it is a positive number.
4. True. The multiplicative inverse of a negative number is the number you would multiply by to get 1. Since you have to eliminate the negative to get a positive 1, then you would have to multiply by a negative.
5. True.
