2012-04-26 20:15:02 -0500 asked a question Simplify multiplication of SQRT()s
sage: a=var('a')               
sage: b=var('b')
sage: sqrt(1/(a*b))*sqrt(a/b)
sqrt(a/b)*sqrt(1/(a*b))
sage: (1/(a*b))*(a/b)        
b^(-2)

to simplify, the expressions under the square root have to be brought together. This is not happening. Is there any workaround?

sage download website doesn't have a pre-build version for ubuntu 11.04. do people just compile from source?
