• Answer is 5
  
  8*1024 = 1000*10000000000 (the product will contain 1 one's)
  3*64 = 11*1000000 (the product will contain 2 one's)
  3 = 11 (contain 2 one's)
  
  Thus, the answer will contain 5
  
  To check:
  if you add them, the sum will be
  10000000000000 + 11000000 + 11 = 10000011000011
  
  the answer contains 5 one's
  
  To verify:
  8 * 1024 + 3 * 64 + 3 = 8387
  8387 in binary is 10000011000011
