leave 8 , now multiply the (first part) with (first part+1). put the result in first
then add (6* first part) with the first digit of (8^2 or 64) that means with 6.if here an excess is present then add that with the result of multiplication.
and at last put 4
...................................................
EX:-
38^2= (3*4) (3*6+6) 4 = (12+2) 4 4 = 1444
128^2=(12*13) (12*6+6) 4 = (156+7) 8 4 =16384
then add (6* first part) with the first digit of (8^2 or 64) that means with 6.if here an excess is present then add that with the result of multiplication.
and at last put 4

EX:-
38^2= (3*4) (3*6+6) 4 = (12+2) 4 4 = 1444
128^2=(12*13) (12*6+6) 4 = (156+7) 8 4 =16384
