    Are you asking \[5\sqrt{10(18-\sqrt{6})}\]?

    So... \[5\sqrt{10}(18-\sqrt{6})\]?

    \[90\sqrt{10}-5\sqrt{60}\] \[90\sqrt{10}-10\sqrt{15}\]

    5*sqrt(60) = 5*sqrt(4)*sqrt(15)=5*2*sqrt(15)=10*sqrt(15).

    Sure... just post another one, unless your question pertains to the one you just asked me.

    Are you trying to rationalize it?

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

    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.
