Making brackets around a function larger

Question

In my project I want to define e as a limit and have the following

$$\lim_{x\to\infty} {(1+\frac{1}{n})^n}$$

but the brackets don't line up properly, the curved brackets don't go around the entire fraction and look messy. How do I correct this?

Any help greatly appreciated.

@AntRobinson It is required (or strongly recommended) to provide typesetable code so that your problem can be easily reproduced by everybody else. Since you're new on the block, I'll let this one slide ;) — Jonathan Komar, Feb 01 '19 at 14:42
@AntRobinson You should just wrap it with minimal code. Add a document class and the relevant commands and environments. For example \documentclass{article}\begin{document}my problem\end{document} Then all anybody has to do is copy and paste your code and try running it to reproduce your problem. — Jonathan Komar, Feb 01 '19 at 14:44

A slight improvement for the exponent placement:

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

An alternative is to use \big-like constructs. The advantage is that you do not have \left \right problems in case your equation is splitted across several lines.

\documentclass[12pt]{article}
    \usepackage[a4paper]{geometry}
    \usepackage{amsmath}
\begin{document}
\begin{equation*}
\lim_{x\to\infty} {\left(1+\frac{1}{n}\right)^n}
\end{equation*}
\begin{equation*}
\lim_{x\to\infty} \bigg( 1+\frac{1}{n} \bigg)^n
\end{equation*}
\begin{equation*}
\lim_{x\to\infty} ( \big( \Big( \bigg( \Bigg( 1+\frac{1}{n} \Bigg)^n
\end{equation*}
\end{document}

Oh you mean like this:

$$ \lim_{x\to\infty} {\left(1+\frac{1}{n}\right)^n} $$

The key points in the code

\left(
\right)
