And just to clarify

So then had the problem been

the answer would look like this?

Thus the final answer would be ? - May 31st 2008, 07:05 AMTheEmptySet

Yes that is correct. - May 31st 2008, 07:40 AMcmf0106
And lastly these two examples, they will both have the same radicand and index.

Do these look correct as well?

1.

2. If this one is correct it would seem that the number will always be just a regular . Because to divide the radicands and index's have to be same. Since the index's must be the same when you subtract one from the other it will result in 0. - May 31st 2008, 07:46 AMTheEmptySet

And if you're wondering why anything to the zero power beside 0 is 1, consider this.

Anything divided by itself is 1, right?

So if you have: .

Since is one, you can sub one in for it in the former equation to get .
