simplify the function, and implement them with two-level NAND gate circuits

Question

$$(A'+C'+D')(A'+C')(C'+D')$$

how to simplify it. i got $A'D'C'$, but it's probably wrong. can someone help me

Answer 1

I'll help you with the simplifying: $$\begin{align}(A'+C'+D')(A'+C')(C'+D') &= C'+ (A'+D')(A'D') \\ \\ &= \color{blue}{C'+ A'D'}\end{align}$$
