For various reasons I have complex exponentials written
both as (for example) (-1)^(2/5) and the equivalent
E^(I Pi/5). How do I convert both forms into the same
form of my choice?
Also I have a variable, say g, defined as (-1)^(2/5) . In
the complex matrices I work with it is important for visual
reasons to have the symbol g itself appear when I need it,
instead of one of its numeric equivalents. Using the usual
substitution rules as I understand them does not seem to
work.
Any tips will be greatly welcomed!
