This is the function: $f(A,B,C,D) = (A' + C)' + D'$, and I also can't use one term's complement to find the other term.
What I did for minterms is:
$(A\cdot B'\cdot C' \cdot D')+(A' \cdot B' \cdot C' \cdot D')+(A' \cdot B' \cdot C' \cdot D') = (A\cdot B'\cdot C' \cdot D')+(A' \cdot B' \cdot C' \cdot D') = m_0m_8$,
but i think it's wrong. Also, I don't get what i have to do for maxterms.
How do I go about solving this?
