There was a simple answer to my question, supplied by Robby Villegas of
Here it is: ComplexExpand.
I missed it because there is nothing like ComplexExpand[(-1)^(3/4)] among
the examples given in The Book. This is a really common need, and I hope
it will appear as an example in future editions.
Thanks, Robby, and also thanks to others who sent home-made operators that
also do the job nicely.
