Welcome to AAC!
1) Show us your best effort so far. This is a 'Homework help' forum; not a 'Homework done for you' one ;).
2) What logical expression?

So now we have 3 expressions.
What have you been taught about logic gates and functions?
Re-read item 1 of post #2.

In particular you need to tell us or provide a truth table for the operation indicated by the circle with a small dot inside in expression number 3. Whatever it is, it is non-standard, and we are not mind readers, so help us out here if you can.

It's looking increasingly like the TS doesn't know what it means, either. They just want someone to work their homework for them. Actually understanding what is being asked isn't needed for that.

Good point. A square box with the symbol inside works for me.

The sad part is that they don't even need to build the best circuit, meaning they don't need to do any simplification. They can simply make individual operation using specific gate, it will take a bunch of gates, but that just manual work, no brain work involved.
