Question 245012
OK.  The idea here is to clear the radical in the denominator.  We can do this by multiplyinig the numerator and denominator by (sqrt(6)-2)---and we get
{5(sqrt(6)-2)}/{sqrt(6)+2)(sqrt(6)-2)} and this reduces to:
{5(sqrt(6)-2)}/{6-4) further simplifying, we have:
{5sqrt(6)-10}/2 or (5/2)sqrt(6)-5


Hope this helps--ptaylor
