$\displaystyle \begin{array}{l} A\backslash B' = A \cap B \\ A'\backslash B = A' \cap B' \\ \end{array} $ Can you use these?

Set-minus works this way: $\displaystyle K\backslash L = K \cap L'$. So $\displaystyle K\backslash L' = K \cap \left( {L'} \right)^\prime = K \cap L$.
hey thanks a lot, now i get it.
