Use the properties listed in Theorem 2.1.1 to show that each pair of circuits in 26–29 have the same input/output table. (Find the Boolean expressions for the circuits and show that they arelogically equivalent when regarded as statement forms.)

Reference:

Given any statement variables p, q, and r , a tautology t and a contradiction c, the following logical equivalences hold.
