Another basic law of Boolean Algebra is the COMMUTATIVE law,
which states: "When inputs to a logic diagram are ANDed or ORed,
the order In which the output Boolean expression is written does not
affect the binary value of the output." For example, AB = BA; A+B =
B+A; PDQ = QPD; C+J+S = J+C+S; etc. The logic diagrams and
truth tables below show that the output Boolean expression of an
AND circuit or an OR circuit can be written without regard to the
order of the factors.
Indicate two ways the output Boolean expressions can be
written for each of the following.
