Hi,

We have been using MAXIMA successfully inside of LON-CAPA for homework problems for several years now - it's a great tool, thanks everybody!!!

While authoring a new kind of homework, I am struggling with "declare" - why does the following (sample) code not give the expected results?

(%i4) declare(x,real);
(%o4)                                done
(%i5) solve(x^3=125,x);
                  5 sqrt(3) %i - 5        5 sqrt(3) %i + 5
(%o5)        [x = ----------------, x = - ----------------, x = 5]
                         2                       2
(%i6) facts();
(%o6)                           [kind(x, real)]

Is there another way to tell "solve" to stay in the real realm?

Thanks!

- Gerd.
