Hi there

the question is

draw logic circuit whose input are boolean algebra x,y,z and the output are

1 if and only if x=y x !=z

1 if and only if x=y x=z

What do you think is the correct approach? Are we talking a function with one output or two outputs? It kinda looks like z is a don't care. I would start with a truth table.

Is this one question with two parts to it? Is it two different questions?

Is this homework? (Sure looks like it.)

What have YOU tried to do to come up with a solution (or at least part of a solution)?

that's an incomplete question as it doesn't show the logic if x <> y.
Yes it does. Review what "if and only if" means.

What is arguably incomplete is that it could be either

1 if and only if (x = y) AND (x != z)
1 if and only if (x = y) OR (x != z)

It is probably the first, but it should be explicit.
