Stefan,
nm=N[(Sqrt[2]+Sqrt[3])^2002,2000];
{digits, numberLeftOfPoint} = RealDigits[nm];
Drop[digits,numberLeftOfPoint-2];
Take[%,4]
{0,9,9,9}
So, 2 digits before point are 0,9 and the two digits after it are 9, 9.
I must confess to some surprise at the great block of nines, but since they
are followed by 7405908 they seem to be correct.
