Hmm!!

0^0 is undefined.

Anything to the power of 0 is 1.

[Edited]

And here's why.

Let's start with powers of 3s because they are easy.

Let's first assume 3^0 is 1.

 

So...

3^0 =1.

3^1=3.

3^2=9.

3^3=27.

3^4=81.

 

Now as you can see, a number is 3 times greater than the number before it. Here's what I'm talking about.

3^2 is 9 and 3^3 is 27. It is obvious that 27 is 3 times greater than 9. This is the same with other numbers that is in the

"3-to-the-what power" form. 

 

So if you think about it, shouldn't 3^0 be 1?

Because we know that a number is 3 times greater than the number before it. 

And 3^1 is 3. So we have to divide that by 3 to get "3^0."

 

3/3 is 1. 

So 3^0 is 1. 

 

This concept can be hard to understand with one example. 

 

But think about it. A similar rule applies to any other set of exponents with the same base. 

2^1 (That 's 2) divided by 2 would get us 2^0.  And 2^0=1. See a pattern?

So you see that you can divide a number with an exponent by its base to get the number that has an exponent 1 less than the original number's exponent. (example: 2^2 and 2^1.  2^1 has an exponent 1 less than 2^2. )

 

And that's my explanation.

There are probably many simpler and better-to-understand explanations out there...

Correct me if my explanation is wrong. I often get things mixed up in explaining things.

The Google calculator says 1. 

This calculator says 0.

Which one is right?

WolframAlpha is a better "Authority" on these matters. Try it and says 0^0 ="undefined".

Thanks, Guest.

Sorry Alan. (I think I've said that the last time I've made a mistake on an explanation)

So long as you learned from your mistake that is all that is important :)
