Hi. You can try to redefine i:=0 and see if get the desired behavior.

You have solved nothing yet from nothing to pass QA !

Hi Jim. Actually your dilemma isn't trivial and the solution that you found it's complete in the sense that you extend over the integers an operation only well defined for the natural numbers. For integers, rationals, reals, complexes, vectors, matrices, tensors ... are only conventions based on definitions by convenience, very very good ones ... but not theorems.

For example Maple have the function surd for deal with roots with integers when the usual convention doesn't work. Because power don't commute have two inverses, one by the left and other by the right, roots and logarithms, complicating the things. This is the help for the surd function from Maple website:

As you can see, if you ask to Maple for convert surd, it returns just x^(1/n).

So, you can define your own function pow3(x) = x^3 * (x > 0). Or maybe more general some CheckPos(x) for make more readable your expression.

Best regards.
Alvaro.

... do some effort:
split that monster, zap subscript, make minimalist like visiting doctor.
