algebra exponents and fractions
I could be over thinking or tired... But I am to embarrassed to ask my prof. this probably very simple algebra rule I am ignorant of... Also this is just a snip-it from a inductive proof example.
Say you have something like this
My question is what algebra rules or rules of fractions allow this? In other words what computation is going on? I can agree that the 3 should cancel out
But wouldn't that mean it be something like this
or more accurately
and not this?
