i dont see how answer is 4it should be 8...using the double-dabble simple method of converting decimal to binary by repetedly dividing by 2, we get 1 as remainder 8 times. becoz the result is 8387 in decimal and 10110011101001 in binary

Consider the binary representations of all three terms:(1) 8*1024 = 2^3*2^10 = 2^13 which is 1 followed by 13 zeroes.(2) 3*64 = 2*64 + 1*64 = 2^7 + 2^6 which is 1 followed by 7 zeros added to 1 followed by six zeroes.(3) 3 = 2^1 + 2^0 and equals 1 followed by 1 zero added to 1 followed by no zeroes.Since all the ones have different place values, and none overlap, we do not have any 'carrys', and there is a total of FIVE ONES in the binary representation.
