I was messing around in IRB and I decided to make a $n^{th}$ root function and noticed that for very large roots of numbers, the answer always converges to $1$. It has been a while since I have done any work with infinite series but could someone explain why this is, or offer a proof. (The most similar thing I could think of is the proof of $.9$ repeating equaling $1$)
Is the infinite root of any number equal to $1$?

0The list of numbers you get by taking the $n^{th}$ root for increasing values of $n$ is called a sequence and not a series. – 2012-05-17

0Let's say of any *positive* number for sake of definition. – 2012-05-17
