Simplify the Boolean expressions below, using DE MORGAN'S
THEOREM, the DOUBLE NEGATIVE law, and the ASSOCIATIVE
law.
a. (J + K)(L + M)
b. (R + S)(D + E)
c. DE+(R + S)
d. X+Y+FG
a. J K+L+M

Often, Boolean expressions cannot be simplified until the
b. R+S+D E
expressions have been converted to another form. The
c. DER S
DISTRIBUTIVE law is used to convert Boolean expressions from
d. X Y FG
one form to another. The DISTRIBUTIVE law is illustrated on the
