okay i somewhat ubderstand 1. i just don't understand where u got 1/10. other than that i get it. & on problem 2, i am very lost. where did the 3 come from in between 5 and -5
oh nevermind, i figured out the 1/10 in the 1st problem but i still don't follow the second one

Does this clarify things? & on problem 2, i am very lost. where did the 3 come from in between 5 and -5 I applied rules of exponents:
yea i got the 1/10 after i posted i didn't understand. but problem 1 i understand. now on problem 2, i see what you did with the 3. i have 1 question though. Will all the threes cancel out? or is there something else i am missing?
nevermind i got problem 2 if any1 cares the answer was: 15625/7776
