I'm supposing that the following rather odd result has something to do 
with Mathematica being concerned that g or r (or k?) might be complex 
numbers?

   In[151] := 

         f1 = g (g/r)^(k-1);  

         f2 = g^k/r^(k-1); 

         f1/f2 // FullSimplify

   Out[151] =  g^(-k)  (g/r)^k   r^k  

But shouldn't Mathematic be able to simplify this to unity nonetheless? 
-- maybe without even invoking Simplify?
