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:
\[
\boxed{e}
\]
