Are you trying to rationalize it?

OpenStudy (anonymous):

i don't know. i think i just need to simplify it

OpenStudy (anonymous):

It is basically simplified already. Rationalize means that there can't be any roots in the denominator.

OpenStudy (anonymous):

yes - rationalize it please

OpenStudy (anonymous):

sqrt(5)/(18+sqrt(3)). Multiply both the top and bottom by 18-sqrt(3).
On the top, you have sqrt(5)(18-sqrt(3)). On the bottom, you have 18^2-3. I hope you can simplify from here.
