First, you omitted something. Second, I wonder how you got your answer. My Mathematica 4.1 for Max OS X (quite correctly) produces: In[1]:= Solve[{k*.01^p==10,k*.1^p==1},{k,p}] From In[1]:= Solve::tdep: The equations appear to involve the variables to be solved for in an essentially non-algebraic way. Out[1]= Solve[{0.01^p*k == 10, 0.1^p*k == 1}, {k, p}] The message should be self-explanatory. Solve is not meant to solve non-algebraic equations. (This topic has been discussed a countless number of times here and if you need more explanation just look in the archives or read the online help).
