Comment #1 on issue 2308 by asmeurer: Rename or refactor Add.primitive()
http://code.google.com/p/sympy/issues/detail?id=2308
Well the name is not really cryptic, since that is the mathematical
definition of primitive. See
http://en.wikipedia.org/wiki/Gauss%27s_lemma_(polynomial).

In [ https://github.com/sympy/sympy/pull/230 ] this gives:
h[1] F=1/x/(1-x)
h[1] f=F.diff(x)
h[1] integrate(f, (x, 1-d, d))

Should anything happen to `2**(1/3)*2**(1/4)*6**(1/2)`?

Comment #1 on issue 2305 by gdrummo...@gmail.com: Integer(3).sqrt() == 1
http://code.google.com/p/sympy/issues/detail?id=2305
The docstring says: Compute integer square root of `a`. It also uses
an isqrt function from mpmath.
Perhaps the method should be renamed to isqrt

I don't like symbols('x, y, z') because it is needlessly verbose. I know

Hmm. So I guess it's not obvious what the simplest form is. For example,
that can also be represented as 2*1458**(1/12).
