A major improvement to a package I have posted at
http://library.wolfram.com/infocenter/MathSource/705/
is now available from this URL.

Normally Mathematica refuses to use a concise format of the following:


In[1]:=  (x y x)^2 + Sqrt[2 w u v]

Out[1]=  x^2  y^2  z^2  + Sqrt[2] Sqrt[w] Sqrt[u] Sqrt[v]


The package includes a function called PowerTogether that can use 
assumtions to give:

In[2]:=  expr = x^2  y^2  z^2  + Sqrt[2] Sqrt[w] Sqrt[u] Sqrt[v] ;
           PowerTogether[ expr, u>0 && v>0 ]

Out[2]=  (x y x)^2 + Sqrt[2 w u v]


The latest version of the package is very powerful!
