Hi all,

I'm looking for an automated way of solving (generally concrete) equations (of real or complex numbers), typically involving roots of 2. I've found that field_simplify (or field_simplify_eq) works very well for my purposes, except that it doesn't know that (sqrt x)^2 = x.

Is there any tactic that is like field_simplify but can deal with roots? (Are there any tactics to deal with roots?) If not, any thoughts on how difficult it would be to extend field_simplify to handle roots?

Thanks,

Robert Rand
