SQRT(a);



Just started using Maxima, and I'm having a little problem... Well, two 
problems.

The first problem is that when I take SQRT(a), where a is a large 
integer (in this case, 2220223), I just get back SQRT(2220223).  Does 
this mean a doesn't have a square root?

The second problem is that what I actually need to do is find the square 
root of a mod n, where n is 20490901.  Any tips on how to do that would 
be appreciated..
