1. Hey,

Basically I don't understand how they have minipulated the numbers, in what is attached, but thankfully it's really short

Thanks (sorry for asking so many questions just got test next week and the suggested textbook is useless i find, and the lecturer says he's too busy to help us)

2. Hehe, I think you forgot to attach it ^_^;;; ...

Edit: Ah, there we go.

Well, hmm...

From the laws of exponents:

ax+1 = ax * a1 = a*ax

The manipulation isn't strictly necessarily (although it is just standard indices), the general result is
d/dx (ef(x)) = f'(x)ef(x)
