Question 117318: This question is about simplifying by adding like terms. I don't think I can duplicate the question here in a simple way because I can't show exponents and negative exponents. I have the answer to the problem (5xsquaredycubed) but don't know why that is the answer.
If you have access to seeing this problem, can you please help? If not, then I can try to "spell it out" if needed.
Thanks for your help.
