I was told that any number raised to the zeroeth power is equal to 1. What about zero raised to the zeroeth power? Is that 1 or 0? So I tried to investigate...

In series, it is always taken to be 1, so that you can write a series expansion compactly:

For example, the geometric series:

is true at x=0 only if we define 0^0=1.

Atleast I think?

my teacher just told me x^0 =1 (where x= a number greater than 0) but 0^0=undefined.

Ay, 0 is an exception.

I don't know how to put maths in my posts, so I'll explain in a different way.

3(4) = 81 3(3) = 27 3(2) = 9 3(1) = 3

Not that everytime we go down, we divide with x (in this case 3).

81:3 = 27:3 = 9:3 = 3 So 3:3 = 1, 3(0) = 1

Use a different number, and you will get the same result

4(3) = 64 4(2) = 16 4(1) = 4 --> :x (4) So 4(0) = 1

But try the same trick with zero.

0(3) = 0 0(2) = 0 0(1) = 0 --> :x (0) So 0:0 = 0

I prefer physics.
