I came up with 6sqrt5 I know it's wrong. I think I messed up the breakdown of the sqrt of 125

**drwls**, Sunday, January 9, 2011 at 6:42pmsqrt(9*5) + sqrt(4*5) + sqrt5 - sqrt(25*5)

= (3 +2 +1 -5)sqrt5 = sqrt5

**Damon**, Sunday, January 9, 2011 at 6:44pmsqrt (9*5)+sqrt(4*5)+sqrt(5) -5 sqrt(5)

3 sqrt(5) +2 sqrt (5) + 1 sqrt(5) - 5 sqrt (5)

that is

1 sqrt(5)
