  • If the problem is with latex, see tex.stackexchange.com/questions/103508/…. If the problem is specific to beamer, The usual answer is "Don't do that in beamer." Nov 12, 2014 at 21:07

Use the shorthand notation

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, \[\det{A} = 0.\]
