Please simplify: Very confused, have many problems like this and need some guidence. Thanks!
The problem has been solved before. See following link for explanations.
I have added the following clarification for Carmin. It is reproduced here in case you are also interested.
=25 a14 a-5
the denominator 2 in the fraction (7/2) is an exponent and not a simple number. This is probably from where you got the 16.
So the 16 is not part of the answer? It's just 25 a^9?
