Im not guessing.
Im trying to understand what you mean by exponation rules.
As far as I can imagaging it cannot be done the same way as you
described the sum problem.
Try with multiplication first. If you can do multiplication, then
exponentiation should be clear.

Oke, 

Just to be sure.

I only have to use suc and pred ?

I think you want something like this :

x + 0 = x
x + y = succ x + pred y
