 Posted: Fri Apr 12, 2002 1:04 am    Post subject: 8 Let N=9^8^7^6^5^4^3^2^2002. So x=(10^N+11)+((10^N+11)*4)=(10^N+11)*5. N is so unimaginable BIG that the 1 in front is very far away from the 11 in the end. So no overlapping, and since 3 divides anything whose sum of digits is (in this case 15) divisible by 3, there you have it.
