leave 7 , now multiply the (first part) with (first part+1). put the result in first
then add (4* first part) with the first digit of (7^2 or 49) that means with 4.if here an excess is present then add that with the result of multiplication.
and at last put 9
...................................................
EX:-
37^2= (4*3) (4*3+4) 9 = (12+1) 6 9 = 1369
117^2= (11*12) (4*11+4) 9 = (132+4) 8 9 = 13689
then add (4* first part) with the first digit of (7^2 or 49) that means with 4.if here an excess is present then add that with the result of multiplication.
and at last put 9
