Hello,
I found
sage: abs(sqrt(x))
sqrt(abs(x))
much better than
(%i1) abs(sqrt(x));
(%o1) sqrt(x)
We discussed in #15605 that variables in the symbolic ring should be
thougt as complex variables (if not specified otherwise). The maxima
version is wrong when x is real negative.
What is the answer to
sage: sqrt(abs(x)**2) == abs(x)
sage: abs(x**2)
sage: (-1)^(2/3) # see ticket 15605
