Answer: A, C, D and E
Step-by-step explanation:
You would have to add a positive 6 to the negative 6 to get zero. Lets say you have -2 in order to get it to zero or just any positive number, you have to add a positive of the same value or higher to be able to get it there. I hope you understand that.
5^2 = 25
3^0 = 1 (anything that is exponented by 0 is 1)
25 - 1 = 24
24 is your answer
hope this helps
