Question

Let  \[X = A \overline{ BC} + B\overline{ CA} + C\overline{AB } .\]   Evaluate X for  A = B = C = 0.

Answer 1

Given:
Output  

\[X = A \overline{ BC} + B\overline{ CA} + C\overline{AB } .\] 

A = B = C = 0

\[X = 0 . ( \overline{{0 . 0)}} + 0( \overline{{0 . 0)}} + 0 . ( \overline{{0 . 0)}}\] 

\[       = 0 .  \bar{0} + 0 .  \bar{0} + 0 .  \bar{0}\] 

\[       = 0 . 1 + 0 . 1 + 0 . 1\] 

\[       = 0 + 0 + 0\] 

\[       = 0\]
