How to convert nand logic gate become the other logic gates, for example nand logic gate to NOR, Ex-Or and Ex-Nor logic gate.

1.) NAND logic gate into NOR logic gate
Truth table
A

           Boolean equation 
     Y = NOT{ NOT[ NOT( A AND A ) AND NOT( B AND B )] AND
     NOT[ NOT( A AND A ) AND NOT( B AND B )] }


2.) NAND logic gate into Ex-OR logic gate
     Truth table
