From what I understand of this question if you keep breaking it in half you get: 4, 8, 16, 32, 64 etc. Which is 2^n+1
I'm just not sure where to go from there...
Is it possible to share a four fingered Kit Kat equally between 5 people if you can only break any one piece in half?
Prove whether it is possible or impossible.

Equally? so for pieces have to be equal when broken.
4^n n=1,2,3,4
so the question is when this will be a multiply of 5? So then, the last digit will be a 5 or 0. Can four to any power give that last digit?

forget this post, I will think on it later. My mind is clogged now with other matters.
