In school you were taught that 0^(1) = 1/0 = 0 ?
We know that 1^1 = 1, so by binomial expansion
1 = 1^1
1 = (1+0)^1
1 = 1 * 1^1 * 0^0 + 1 * 1^0 * 0^1
1 = 1 * 1 * 0^0 + 1 * 1 * 0
1 = 0^0 + 0
then 0^0 = 1
This may not be strictly true, but it is at least a useful value. Like 0! = 1.

You must find the limit as x approaches 0 of f(x) = x^x. Use can use l'hopitals rule or just put in a small number for x and see what happens. If x=.001 then x^x is close to 1.
X can not be negative because of fractional negative values. If x = 1/2 then x^x = 1 / sqrt(1/2) and you can not take the square root of a negative number.

It's 3am here and I can't find a good answer to the exact point, but in the limit x→0 we have that x^x = exp(x ln x).
In that limit (x→0+) the argument of the exponential goes to zero, since x goes to zero faster then ln x goes to inf. This leaves us with exp(0) = 1.
ANY exponential function is defined only when the base in bigger or equal zero. In that case it's when x>=0. You can calculate single values for negative bases, but they're not a function anymore (at least not in R).

It is indeterminate (you cannot determine the value).
The rule for limits is that the limit must be the same, regardless of the "direction" you take to get there.
Bluntly, a limit must be unique.
As soon as you can show more than one limit value, then the value does not exist and the operation cannot be determined.
Let's look at n^0
and allow n to get closer and closer to zero (for example, n = 1/2, 1/4, 1/8...)
The value of n^0 will be 1 for all values of n, therefore the limit is "1"
If this is valid, then 0^0 = 1
Now consider 0^n
and allow n to get closer and closer to zero.
The value of 0^n will be 0 for all values of n, therefore the limit is "0"
If this is valid, then 0^0 = 0
Both operations are valid, yet they reach a different limit. Therefore the limit does not exist.

1 = (y^x)/(y^x) = y^(xx) = y^0
But I don't think y can be 0, cause 0^0 is undetermined.
If you calculate, for instance, .0001^.0001, you'll see the result is .99, but not 1.

what is 1 to the power 2..1*1 ...so...1^2 =1
what is 2 to the power 3... 2*2*2 so 8
then what is 0 to the power 0?
it is 0
Physically speaking, it is nothing..i mean..it is saying like nothing has happened...i.e 0(nothing) raised to the power 0(nothing).
some call it indeterminate form also..
