((p∨(¬q))∧(r∨(¬q)))⇒(¬(p∧q))
$$\left(\left(p \vee \neg q\right) \wedge \left(r \vee \neg q\right)\right) \Rightarrow \neg \left(p \wedge q\right)$$
Solución detallada
$$\left(p \vee \neg q\right) \wedge \left(r \vee \neg q\right) = \left(p \wedge r\right) \vee \neg q$$
$$\neg \left(p \wedge q\right) = \neg p \vee \neg q$$
$$\left(\left(p \vee \neg q\right) \wedge \left(r \vee \neg q\right)\right) \Rightarrow \neg \left(p \wedge q\right) = \neg p \vee \neg q \vee \neg r$$
$$\neg \left(p \wedge q\right) = \neg p \vee \neg q$$
$$\left(\left(p \vee \neg q\right) \wedge \left(r \vee \neg q\right)\right) \Rightarrow \neg \left(p \wedge q\right) = \neg p \vee \neg q \vee \neg r$$
