Well, how real is it? Is f something found in the wild? Doesn't seem to
be, since f is constructed as ratsimp(ansp). It makes a difference in
this case since ratsimp rearranges the expression so that the exponents
are different, which means that reconstructing the original ansp from f
cannot be carried out by considering exponents alone.
But that may well be beside the point. What are some expressions which
you have actually encountered?
