(p⇒(q∨r))⇔((p∧(¬q))⇒r)
$$\left(p \Rightarrow \left(q \vee r\right)\right) ⇔ \left(\left(p \wedge \neg q\right) \Rightarrow r\right)$$
Solución detallada
$$p \Rightarrow \left(q \vee r\right) = q \vee r \vee \neg p$$
$$\left(p \wedge \neg q\right) \Rightarrow r = q \vee r \vee \neg p$$
$$\left(p \Rightarrow \left(q \vee r\right)\right) ⇔ \left(\left(p \wedge \neg q\right) \Rightarrow r\right) = 1$$
$$\left(p \wedge \neg q\right) \Rightarrow r = q \vee r \vee \neg p$$
$$\left(p \Rightarrow \left(q \vee r\right)\right) ⇔ \left(\left(p \wedge \neg q\right) \Rightarrow r\right) = 1$$
