Question: Unable to evaluate


I need to solve some  transcendental equations, using Maple 16 which i need to transform or bind with java later. My problem is I cant evaluate.

Equation I would like to evaluate is  k= ln((M-m)/m(k-1))offcourse I  defined m and M, prior to c.
Both  eval(k) and evalf (k)  only return k,  I need value for further calculations.

I went through settings and tutorials ,  however it didn't work.  So I also traded to evaluate k= root( k), the return value was here also k.

Can someone please help me by telling me where the problem might be, or what am I doing wrong?

Thanks a lot
