Solving z^n=a+ib using only radicals of positive real numbers
"The answer to your question follows directly from the paper mentioned above." above is not constant across platforms and viewing modes. Could you please employ some more invariant term, so I can know what paper you mean?

Also posted to m.se  you should put a link at each site to the question at the other site.

Actually, I think this is the "Heillbron triangle problem", see en.wikipedia.org/wiki/Heilbronn_triangle_problem

This sounds something like the problem of packing $n$ identical circles into a circle. So far as I know, the optimal solution for that problem is not even known for $n=12$, so a billion may be a bit much to ask for.

How to prove that two univariate polynomials are always algebraically dependent?
If you're going to do this, the way to do it is to give your proof, so we don't waste our time and yours by telling you something you already know.

Is a particular type of question about certain infinite sets still being asked?
How about the largest infinite set of cardinality less than the continuum?

But is there a specific entire function which is known to have infinitely many nonequivalent factorizations, but for which it is not known whether that infinity is countable?

construct totally real cubic fields
Sorry, still don't follow. $u+1$ has norm $1$, but you are allowing "up to multiplication by $1$", so look at $u1$. Well, that's no good because it's negative, but one of its conjugates is positive, so take that positive conjugate to be $\sigma_1(u1)$. Or is it that you want to assign the $\sigma_i$ first, so that one assignment works for all units?

Enumerating ways to decompose an integer into the sum of two squares
@pts, I think for $13^4$ you have to look at $(3+2i)^4$, $(3+2i)^3(32i)$, and $(3+2i)^2(32i)^2$, which give rise to $120^2+119^2$, $156^2+65^2$, $169^2+0^2$, respectively. But, honestly, why do you not work these out for yourself?

I don't understand your objection, Ted. That $u$ is a unit, it is positive, and its conjugates are negative. What desired property is it missing?
