You rationalize the denominator.

Your expression looks like this

$x/sqrt(2)$

The only option available to you when it comes to simplify this expression is to rationalize the denominator.

You can do this by multiplying the numerator and the denominator by $sqrt(2)$ to get

$(x * sqrt(2))/underbrace((sqrt(2) * sqrt(2)))_(color(blue)("=2")) = (x * sqrt(2))/color(blue)(2)$

Thus, the simplified form of your initial expression is

$x/sqrt(2) = color(green)( (x * sqrt(2))/2)$
