(1001)3
(1000+1)X3
Since, (a+b)3 = a3+b3+3ab(a+b)
(1000)3+(1)3+3X1000X1(1000+1)
1000000000+1+3000X1001
1000000000+1+3003000
1003003001

ANS. 1003003001

(1001)^3

= ( 1000 + 1)^3

[ ( a +b) ^3 = a^3 + b^3 + 3ab(a+b)]

= (1000)^3 + (1)^2 + 3(1000) (1)( 1000 + 1)

= 1000000000+ 1 + (3000 × 1001)

= 1000000000 + 1 + 3003000

= 1003003001
