How to simplify expressions with variables and unlike exponents?

Posted on 2014-04-16 06:36:00 in Math by BLUE'S KID

HI, I am doing my math homework and have stumbled upon a category of questions... I am asking this question again because I am not sure if I sent the first one to the correct place...

For example, a^7b^5 + a^5b^7

Would I multiply the terms a and b to get:

ab^12 + ab^12

???

Thanks for the help! :D
