1. Answer:

   (a+b) ² = a²+b² +2ab

   (1008) ² = (1000+8) ²

   => 1000² +8² + 2x 1000 x8

   => 1000000 + 64 + 16000

   = > 1016064

   HOPE THE ANSWER HELPS YOU.

2. Answer:

   The expansion (a+b)2 = a2 + b2+2ab

   So,

   The number becomes (1000+8)2 which becomes from the above expansion

   (1000)2 + (8)2 + 2(1000)(8)

   10,00,000 + 64 + 16,000

   10,16,064.
