PLEASE HELP!!

Problem #3 11 pt. Implement the function F = ((A'+B') + (BC+D))' using only NAND and N (ATB) + (BC+D))' using only NAND and NOR gates. In order to receive credit, your answer must be correct AND use good style. This includes good docu practices - your implementation should be easy to verify. Needlessly inefficient circuits down.
