Or better n^0 = the number of functions from the empty set (cardinal 0) to the set with cardinal n. This justifies also 0^0 = 1 (there is one (empty) function from the empty set to the empty set). > along > with 'n/0 is 'undefined''.

Why? It is usual that a function (like y = 1^x) can have the same value for different argument. From (-5)^2 = 5^2 you will not infer that 5 = (-5), right? From sinus(x) = sinus(pi - x) you will not deduce that x = pi - x, right? > If they can be substituted > in the above equation, without changing a resultant of > calculations (they are embedded in), then they must somewhere > somehow in fact be identical in some way or condition.

I am using the name 0, 1, ... for the usual numbers. 1 is different from 0 for the same reason that 1 cup of coffee is different from 0 cup of coffee, or that 1 joke is different from 0 joke ...
