In[21]:= ?PowerExpand PowerExpand[expr] expands nested powers, powers of products, logarithms of powers, and logarithms of products. PowerExpand[expr, {x1, x2, ...}] expands expr with respect to the x1. Use PowerExpand with caution because PowerExpand does not pay attention to branch cuts. In[22]:= PowerExpand[ Sqrt[Meter^2/Second^2] ] Out[22]= Meter ------ Second I hope this helps. --Ian ----------------------------------------------------------- Ian Collier Technical Sales Support Wolfram Research, Inc. ----------------------------------------------------------- tel:(217) 398-0700 fax:(217) 398-0747 ianc at wri.com Wolfram Research Home Page: http://www.wri.com/ -----------------------------------------------------------
