Find $\displaystyle\lim_{n\to\infty}\frac{\sqrt[n]{n}}{\sqrt[n+1]{n+1}}$.

$\sqrt[n]{n}=e^{\frac{\ln n}{n}}$ and $\frac{\ln n}{n}\to 0$ as $n\to\infty$.

So are you saying that the answer is $\displaystyle\frac{1}{1}=1$?$\sqrt[n]{n}=e^{\frac{\ln n}{n}}$ and $\frac{\ln n}{n}\to 0$ as $n\to\infty$.

Do you know this limitFind $\displaystyle\lim_{n\to\infty}\frac{\sqrt[n]{n}}{\sqrt[n+1]{n+1}}$.

Do you know this limit

$\displaystyle\lim _{u \to \infty } \sqrt{u}=~?$

It's 1.

What is the answer to the OP?It's 1.
