   I'm guessing that you are using wxmaxima which displays   
   %pi   and   pi   
   the same.  unfortunately.   As the lower-case Greek letter.   
      
   %pi is the name for the ratio of the circumference to the   
   diameter of a circle.   pi is   
     some other symbol like pi, pj, pk.   
      
   You computation produced sqrt(%pi)/sqrt(pi).   
   Which is why it doesn't reduce.  To fix your program, replace pi   
   by %pi.  Then the answer comes out 1.   
      
   Good luck.
