I really need help on adding and subtracting exponents:confused: I need the help for and assignment in math due tomorrow and I still have 3 questions left:(

The questions are:

5^2+5^3

3^5-3^3

5^2+2^5

Thanks:D:):o

1. 5x5+5x5x5=
25+25x5=
25+125=?
technically, all of them are like that. You just have to re-write after every step. Trust me, it works and helps. I have to do this too at school. :P
