Referencing Equations in TeX (Hyperlink)

Code

\label{} and \eqref{} can be used to reference equations. It is also possible with \ref{}, but the difference from \eqref{} is that it does not automatically put parentheses.

$$
\begin{equation}
(a+b)^{2} = a^{2} + 2ab + b^{2}
\label{a}
\end{equation}
$$

곱셈공식 $\eqref{a}$를 적용하면,

The code like $\TeX$ above is displayed as follows:

$$\begin{equation} (a+b)^{2} = a^{2} + 2ab + b^{2} \label{a} \end{equation}$$

By applying the multiplication formula $\eqref{a}$,
