In the current 9.0.1, I got

In[3]:= Solve[K == Sqrt[(M - 1)/M], M]

Out[3]= {{M -> 1/(1 - K^2)}}

Version 5.2 solved it, too.

Since Mathematica is used a lot for creating large programs, it has to be more literal. Wolfram|Alpha makes assumptions to make easy calculations easier.

Solve is oriented toward polynomial equations. There are some extensions.

Since Mathematica built-in names begin with capital letters, we recommend that user names begin with lower-case letters. Clashes can produce odd results.

In[1]:= ?K

K is a default generic name for a summation index in a symbolic sum.

In[2]:= ?M

Information::notfound: Symbol M not found. >>
