# Latex matrix of real numbers R^3x3

I trying to write R^3x3 (for a matrix 3 columns and 3 rows) in Latex using this:

 \mathbb{R}^3x3


But all this does is put the first 3 in the power and then writes x3 next to it in normal text.I must be searching wrong on google, so I can't find it.

Also tried some stuff like:

\mathbb{R}^(3x3)
or
\mathbb{R}^[3x3]


But this gives nothing

Any help is appreciated.

Thanks

• Have you tried \mathbb{R}^{3x3}? – Terje D. Mar 20 '14 at 19:53
• just tried it a minute ago was going to tell that I found it. Thanks – Denis Davydov Mar 20 '14 at 19:55

You should put 3x3 in {} like:
$\mathbb{R}^{3x3}$

$\mathbb{R}^{3\times3}$
