1. 1061208

   Let us rewrite (102)3 as (100+2)3

   Now using the identity (a+b)3=a3+b3+3ab(a+b),

   we get(100+2)3=1003+23+[(3×100×2)(100+2)]=1000000+8+(600×102)=1000000+8+61200=1061208

   Hence, (102)3=1061208

2. Answer:

   (x+y)^3 = x ^3+ y^3 + 3x^2y + 3xy^2

   (100 +2 )^3

   1000000 + 8 + 60000+ 1200
