Due to weight of each bit we have;8=1 one in binary form1024=1 one ie for 2 raise to 10 th position 3=2 ones and there are 2 threes in expression therefore 4 ones64=1 one means total 7 ones.Why to convert to binary unnneccesarily?

8*1024 + 64*3 + 3 = 8387 8387/2 then remainder = 1 4193/2 then remainder = 1 2096/2 then remainder = 0 1048/2 then remainder = 0 524/2 then remainder = 0 262/2 then remainder = 0 131/2 then remainder = 1 65/2 then remainder = 1 32/2 then remainder = 016/2 then remainder = 0 8/2 then remainder = 04/2 then remainder = 02/2 then remainder = 01/2=0 then remainder = 18387= 10000011000011so overall we have 5 1'sThank you

8*1024 + 3*64 + 3= (2^3*2^10) + (2^1+2^0)*2^6 + (2^1+2^0) = 2^13 + 2^7 +2^6 + 2^1 + 2^0 Hence 5
