a) Let a3a2ajao and b3b2b1bo be 4-bit binary numbers, where a3 and b3 are the most significant bits and an and bo are the least significant bits. Write a Boolean formula that evaluates to true if aza2010o > b3b2bibo, and false otherwise. b) Let a2aja, and b2b1bo be 3-bit binary numbers, and let C3C2C1C0 = 22ajao + b2b1bo be 4-bit binary number. For example, 1011 = 101 + 110. Write boolean expressions for c2, ci, co. You should also be able to write a formula for c3 but no need to submit it. c) Let agaga7a6a5a4a3a2a1ao be a 10-bit binary number. Write a boolean formula that evaluates to true if an even number of digits of this number is 1, and false otherwise
