breaking the no in 2 halves and then putting it according to the formula given above
(1000 + 3)3= (1000)3+3*(1000)2*3+3*1000*(3)2+(3)3
= 1000000000 + 9*1000000 +3000*9 +27
= 1000000000 +9000000 +27000+27
=1009027027
(1000 + 3)3= (1000)3+3*(1000)2*3+3*1000*(3)2+(3)3
= 1000000000 + 9*1000000 +3000*9 +27
= 1000000000 +9000000 +27000+27
