x%5E3%2Ax%5E-5
becomes
x%5E%283-5%29
which becomes
x%5E-2
which can be interpreted as
1%2Fx%5E2
-----
in general
x%5Ea%2Ax%5Eb+=+x%5E%28a%2Bb%29

-------------
x%5E3+%2A+x%5E-5
When you multiply terms, you add exponents, if it's the same variable. In this case it is, both terms are powers of x.
=x%5E%283-5%29
=x%5E-2
=1%2Fx%5E2
