hmm, so negative numbers cannot be exponentiated by fractions (like -10^0,5=imaginary number).. well OK, thanks. We haven't learned yet how to calculate things like 10^0,5 without calculators or programs yet. Thank you, again.
PS. Heh, these are interesting numbers. So basically (-2)^(-2)^(-2) have multiple answers depending on how u interpret it (I always thought you had to solve these issues in "(-2)^(-2)^(-2)= (-2)^0,25" this way, and not this; "0,25^-2" way)..
The standard interpretation is (-2)^[(-2)^(-2)].

Is this a typo? I thought the only solutions were 2i and -2i.
hmm, OK. I think I understand this allot better. for example:
10^1/5 solving this would need:
x^5=10
and then u use the 5√ 10 to solve it.
Thinking of it, we HAVE went through this. heh I just forgot it. 10^2/6= 3/1√10 and so on.
And yeah, now that I can see this it is only logical that even exponent fractions are imaginary (square root of -1?) while odd ones are not (3√(-1)=-1*-1*-1=-1).
