task 2 truth table:

A B Out
-------
1 1 1
1 0 0
0 1 0
0 0 1

This circuit is a biconditional and it functions as equivalence, the circuit is only true when the inputs are the same.



task 3 truth table:

A B Out1 Out2
--------------
1 1 0 0
1 0 1 1
0 1 1 1
0 0 1 1

They are the same and Demorgan's Law holds true.
