I. Power Basics
A power/index only applies to the thing that it is attached to. It can only attach to one thing, either:
Consider these:
1. The 3 is attached y.
2. The 3 is attached to the brackets surrounding x
and y log a xn
3. The 3 is attached to the brackets surrounding x
and y.
4. The 3 is attached to the brackets surrounding y.

(x)(y)3 = x(y)3 = xy3
