What do you mean zero to "the" zero?
I see it's written write there the zero and the other zero right there above it. Zero to the zero or zero, zero to the zeroeth power, anything to the zeroeth power equals 1. Zero, though, otherwise for anything else, zero to any power is zero. Besides zero, zero, any number of products of copies of zero is zero. Yet, sometimes: zero to the zeroeth power is better evaluated as one, here as it is the discontinuity for that for everything else X, X^0 = 1.
Here the point is there are two zeroes, zero the scalar and zero the exponent. If being about 1 is an ideal condition, then it is one.
Then in the frameworks like the theory where there are counterexamples, that's basically established on the contingency that all the numbers here simply and well enough about the zeroes, are as to expected continuity of their conditions.
Well now I'm sure I have my ignorance here enough for that, yet, I find Peter and Dan should work to accommodate that intuitively and constructively each has its points, as to axiomatics, those being domain axiomatics or model. Those are then stipulations on the notation as to their general context and simply making clear or pointing out the discrepancy for each.
Then about effects where for those two functions they're each other's discontinuities, it makes there as zero is central for the general usual case where zero is central or original.
x^0 = 1 0^x = 0
These are relevant as generally the parameter estimation sees each as relevant or not contrary to approximation, as they are used with approximating terms in relative (linear) frameworks for the behavior as the value goes to zero, or through zero.
The functions or identities are state without otherwise assumptions as to x which here is the point of discrepancy as to how the other would apply, these identities as functions (i.e., here constants or identities and the identity establish enough their nullity in their frameworks about them).
It seems that if you set x^0 or 0^x it would have the constant value.
Thank you, Ross Finlayson
