Questão 2331078

S = (A B•C)•(A• \(\overline{B}\) )

\(S=\overline{\left(\left(\overline{A}\ •\ \overline{B}+\overline{C}\right)+\overline{\left(A\ •\ \overline{B}\right)}\ \right)}\)

\(S=\ \overline{\left(A\ +B\ •\ C\right)}\ •\ \overline{\left(A\ •\ \overline{B}\right)}\)

\(S=\overline{\left(A+B\right)\ •\ C\ +\left(A\ •\ \overline{B}\right)}\)
