An easy way to convert from binary to hexadecimal is to group binary digits into sets of four, starting with the least significant (rightmost) digits. Pad the most significant digits with zeros if necessary to complete a group of four. Here 1001000010011001 is grouped as 1001, 0000, 1001, 1001. Decimal equivalent of each group is 9 0 9 9. Hence 9099 base 16 is the answer.
