Comment (by gagern):
Replying to [comment:77 jdemeyer]:
> The right way of implementing `radical_expression()` would involve
Galois theory anyway, so perhaps we can rid of `solve()` completely in the
future (it might be feasible to implement that in Sage using PARI).
OK, I can understand that. At a glance I didn't find a ready-to-use
function in the PARI/GP docs, but it's pretty late in the day and I
haven't worked directly with PARI before. If you have some pointers,
please share them.
Feel free to give
[http://git.sagemath.org/sage.git/commit/?id=a5983f73b2acdbdd197f25d07c1fcf14bf1109e5
a5983f7] a positive review and ignore the commits about `via_nf` if you
are not comfortable with those.
