((a⇒b)∧(b⇒a))⇒(a∨b)
$$\left(\left(a \Rightarrow b\right) \wedge \left(b \Rightarrow a\right)\right) \Rightarrow \left(a \vee b\right)$$
Solución detallada
$$a \Rightarrow b = b \vee \neg a$$
$$b \Rightarrow a = a \vee \neg b$$
$$\left(a \Rightarrow b\right) \wedge \left(b \Rightarrow a\right) = \left(a \wedge b\right) \vee \left(\neg a \wedge \neg b\right)$$
$$\left(\left(a \Rightarrow b\right) \wedge \left(b \Rightarrow a\right)\right) \Rightarrow \left(a \vee b\right) = a \vee b$$
$$b \Rightarrow a = a \vee \neg b$$
$$\left(a \Rightarrow b\right) \wedge \left(b \Rightarrow a\right) = \left(a \wedge b\right) \vee \left(\neg a \wedge \neg b\right)$$
$$\left(\left(a \Rightarrow b\right) \wedge \left(b \Rightarrow a\right)\right) \Rightarrow \left(a \vee b\right) = a \vee b$$
