Question:

\[ \lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x= \]

Show Hint

Always remember the standard limit \(\lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x=e\). It is used frequently in limits.

The Correct Option is C

Solution and Explanation

Concept: A very important standard limit is: \[ \lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x=e \]

Step 1:
Compare the given expression with the standard limit. \[ \lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x \] This is exactly the standard exponential limit.

Step 2:
Therefore, directly using the standard result: \[ \lim_{x\to\infty}\left(1+\frac{1}{x}\right)^x=e \] Hence, the required value is: \[ \boxed{e} \]
