Conventionally we do not have radicals in the denominator, so you can do this:

$3/(2sqrt2)*sqrt2/sqrt2 = color(blue)((3sqrt2)/4)$

All I did was multiply using the same radical you see in the denominator of the original fraction as a ratio that equals $1$ .

There's really nothing more you can do here.
