Question

Plese explain neatly and clearly. Thank you so much!

The NAND connective is important because it only takes two transistors to build an
electronic circuit that computes the NAND of two signals:
ww- Vcc
pTq
Such a circuit is called a logic gate. Moreover, it is possible to build logic gates for the
other logical connectives entirely out of NAND gates. Demonstrate this by proving the
1
following equivalences in parts (b), (c), and (d) using the laws of the logical equivalence
and the fact that P ↑ Q = ¬(PA Q).
b. (P ↑ Q) ↑ (P ↑ Q) = P A Q
c. (P ↑ P) ↑ (Q ↑ Q) = P v Q
d. P↑ (Q ↑ Q) = P → Q
