square root simplification



(%i7) e : sqrt(Y) * sqrt(Y/X)$

Either

 (%i9) ratsimp(rootscontract(e));
 (%o9) abs(Y)/sqrt(X)

or

 (%i10) radcan(e);
 (%o10) Y/sqrt(X)

For user documentation, enter ? name; for example:

> ? rootscontract;

If the user documentation doesn't explain why %o9 differs from
%o10, it's a bug.
