Question 269121
 I need to find the Distance between the points ( , ),( , ) 
Using the Distance formula d= sqrt[(x2-x1)^2+(y2-y1)^2 
I get sqrt[(sqrt12-sqrt3)^2 + (sqrt27-sqrt8)^2]
{{{d^2 = (12 + 3 - 2*6) + (27 + 8 - 2sqrt(216))}}}
d^2 = {{{38 - 12sqrt(6)}}}
You didn't show your simplification.
-------------------------
Which i simplified to: 
Sqrt[2(2*sqrt3-sqrt2) 
The answer in the back of my book says: 
sqrt[38-12*sqrt6] 
So what did I do wrong or miss? I can't figure it out.
