In an engineering lecture I'm stuck in this part, this is one of those problems where you know it is pretty dumb but can't get out of it. Here's the link:

Can anyone explain me how they got a simplified Re/re from there?
I divided both of the numbers in that equation and got a (Re+re)/re.
How did they get rid of that "re" in the numerator and simplify it in that form?
Thanks in advance
