Question 60847
It would help if you could say what it is you have to do to this!

Let's assume that you have to simplify it, ok?

{{{10xy/sqrt(2x)}}} Multiply top and bottom by {{{sqrt(2x)}}} and simplify.
{{{10xy*sqrt(2x)/sqrt(2x)sqrt(2x)}}}
{{{10xy*sqrt(2x)/2x}}}  Cancel the x's and divide top and bottom by 2.
{{{5y*sqrt(2x)}}} ...and that's as far as you can go!
