1234H -> 0001001000110100
7856H -> 0111100001010110
AND -> 0001000000010100
NOT -> 1110111111101011

Each digit in a Hexedecimal number represents the 4 binary digits in the same place in the binary equivelent. So to turn a Hex value to Binary, convert each digit one by one and replace it with a 4 digit binary equivelant.

Then you simply Logically AND (Equals positive when both inp0uts are positive) and NOT (Opposite) the results.
