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