Q. Combien existe-t-il de fonctions logiques de 2 variables, dans le contexte d’une logique à 3 valeurs ? Justifier votre réponse
Understand the problem: Step 1: Understand the problem.In a 3-valued logic system, each variable can take one of three values. We need to determine how many different functions can be defined with two variables where each variable can be 0, 1, or 2.
Calculate input combinations: Step 2: Calculate the number of possible input combinations.Each of the two variables can take 3 different values. Therefore, the total number of input combinations for the two variables is 3×3=9.
Determine output possibilities: Step 3: Determine the number of possible outputs for each function.Since the logic system is 3-valued, each function can output one of three values (0, 1, or 2) for each input combination.
Calculate total functions: Step 4: Calculate the total number of functions.For each of the 9 input combinations, there are 3 choices of output. The total number of functions is therefore 39.
Compute 39: Step 5: Compute 39.39=19683.
