Hi,

Yes. Maxima's attitude is that the square root of negative one is an
expression which might have multiple values, rather than just picking one
you hope might be consistent over branch points.
To enforce Maxima to work in the real domain, avoiding to play too much
with complex square roots, one can add at the beginning of the Sage session:
maxima_calculus.eval("domain: real;")
Then the second example in the initial message of this thread yields
[[x == 2/5*sqrt(6)*sqrt(5), y == 16, l == 1/9*18750^(1/6)], [x ==
-2/5*sqrt(6)*sqrt(5), y == 16, l == -1/9*18750^(1/6)]]
instead of an empty list.
Eric.
