    Solución

    Ha introducido [src]
    (p⇒q)⇒((p⇒(q⇒r))⇒(p⇒r))
    $$\left(p \Rightarrow q\right) \Rightarrow \left(\left(p \Rightarrow \left(q \Rightarrow r\right)\right) \Rightarrow \left(p \Rightarrow r\right)\right)$$
    Solución detallada
    $$p \Rightarrow q = q \vee \neg p$$
    $$q \Rightarrow r = r \vee \neg q$$
    $$p \Rightarrow \left(q \Rightarrow r\right) = r \vee \neg p \vee \neg q$$
    $$p \Rightarrow r = r \vee \neg p$$
    $$\left(p \Rightarrow \left(q \Rightarrow r\right)\right) \Rightarrow \left(p \Rightarrow r\right) = q \vee r \vee \neg p$$
    $$\left(p \Rightarrow q\right) \Rightarrow \left(\left(p \Rightarrow \left(q \Rightarrow r\right)\right) \Rightarrow \left(p \Rightarrow r\right)\right) = 1$$
