    does anyone here know how to construct a XOR logic gate by only using AND, OR or NOT gates?

    The exclusive OR function means that C is true if A is true and B false, or A false and B true. Three AND gates and teo inverters will do it.

    Quite easily. The task you have is proving the Boolean identity for this circuit.
