I think this should be:
In [3]: f(3*x, 5*x).d

Would it be useful to add a 'format hint' field to the nodes?
Expressions would remain stored as they are now, but the formatters
could use the hints to adjust the form of the output.
For example, if a user enters sqrt(2), the hint for the Pow node would
indicate 'radical'. If the user enters '2
