I am new in LaTex and need your help to write the following math equation in LaTeX.

First, never use $\Pi$ when you obviously mean $\prod$. Second, I guess dots here between $R_i$ and $ID$ should be centered.
Here is what I got:
\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator{\Dist}{Dist}
\begin{document}
\pagestyle{empty}
\begin{displaymath}
MR(e) = \prod_{(R_i\cdot ID, R_j\cdot ID)}
\underset{\Dist_{sp}(r_i,r_j)\le\delta}{(R_i\bowtie R_j)}
\end{displaymath}
\end{document}
You would probably want to use an align environment
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
\label{cons1}
x_i+w_{mi}&\le X_j &&\text{if $i$ is to the left of $j$}\\
\label{cons2}
x_i-w_{mj}&\ge X_j &&\text{if $i$ is to the right of $j$}\\
\label{cons3}
y_i+h_{mi}&\le y_j &&\text{if $i$ is below of $j$}\\
\label{cons4}
y_i-h_{mj}&\ge y_j &&\text{if $i$ is above of $j$}
\end{align}
\end{document}
You shouldn't use eqnarray in LaTeX, see eqnarray vs align

One of the simplest ways to input an equation into LaTeX is to write something like
Notice how I've used the syntax of LaTeX to format the equation into the way you want - subscripts need the _ key, and I've used { } to indicate "k_p" should itself be a subscript. Also note how to make fractions by using the \frac{}{} command.
