Maxima can't simplify this to 1::

(%i1) 3*sqrt(2)/sqrt(3)/sqrt(6); 3 sqrt(2) (%o1) --------------- sqrt(3) sqrt(6)

----

(%i2) %^2; (%o2) 1

(%i3) build_info();

So is this a bug or one should always use radcan?

I count it as a bug, and a serious one. Radcan shouldn't be necessary for simple cases like this.
