Question

How do you multiply `3 / (2 sqrt2)`?

Answer 1

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.
