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!
