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