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

You should put 3x3 in {} like:

$\mathbb{R}^{3x3}$

or better

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