    Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that produces what you have shown, and please explain what specifically is your problem. It will be much easier for us to help you when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – yo' Nov 12 '14 at 19:05
  • Sir . I have written the code but there is not enough space between rows and column. It looks so congested – user66092 Nov 12 '14 at 19:27
  • Then please edit your question and include the code. – yo' Nov 12 '14 at 19:29
  • Will you help me with this ? I will upload the code in a while? – user66092 Nov 12 '14 at 20:18
  • If the problem is with latex, see http://tex.stackexchange.com/questions/103508/adjusting-space-between-array-rows-and-columns. If the problem is specific to beamer, The usual answer is "Don't do that in beamer." – John Kormylo Nov 12 '14 at 21:07

Use the shorthand notation

\documentclass[]{beamer}
\begin{document}
\begin{frame}
Let $A\in\mathbb{R}^{n\times n}$ and each entry of $A$ admits the value
given by \[A_{jk}=(2)^j(3)^{-k}.\] Then, \[\det{A} = 0.\]
\end{frame}
\end{document}
