Yup Vijay u r correct.. for some reason i was thinking it in a different way.. sorry..:(
Posted by: Sreedhar G At: 4, Nov 2003 8:43:41 AM IST
n = sqrt( m + sqrt( m + sqrt( m + sqrt ( .... ) ) ) )
where n is an integer ) 1, and m=n(n-1)
In this formula if m=6 ..then n should be equal to 3.
Even if we consider m=20..n will be 4.

oops.. i mean greater than 2.
Posted by: Sreedhar G At: 4, Nov 2003 7:06:45 AM IST
Vijay.. the formula fits only for 2 and -1.
try the same for ) 2.
Posted by: Sreedhar G At: 4, Nov 2003 7:05:29 AM IST
Oh ..then the explaination given by u fits the general formula in my posting
:)
Posted by: విజయ్ At: 4, Nov 2003 4:15:48 AM IST
Yes Jeevi, another way is ...
sqrt(2+sqrt(2+...)) = x
so
sqrt(2+x)=x
2+x=x²
so x=2
Posted by: Hytech At: 4, Nov 2003 4:12:42 AM IST
sqrt(2+sqrt(2+.....) = x; 2 + sqrt(2+....) = x2; EQ becomes.. x2 -x -2 = 0; x = 2 or -1. i.e., 2.
