    2. Relevant equations

    3. The attempt at a solution

    Now I wasn't sure how many inputs there are so I just used 2 because I see there are 4 and if there are 4 then there are 16 combinations.So I do not know if my answers are correct. But with 4 inputs the gate H is an ex-or gate I believe. But for 2 inputs I do not think there is a single gate for H
