Simplification of logic function f = (A / + B /) (A / + C /) (B / + C /) (a + B + C) + ABC Written meaning: A / = a non 1. Simplify [logic function] f = (A / + B /) (A / + C /) (B / + C /) (a + B + C) + ABC and write its truth table 2. Truth table of F = AB / + AB / 3. Can questions 2 and 3 of the truth table of F = AB / times AB / continue to be simplified? I always find the truth table of the question strange
