Final answer:
The Boolean function f(a, b, c, d) = (a b c' d')(a' b' c')(a b d)(a' c) can be expressed as a combination of AND and NOT operators on the variables a, b, c, and d.
Step-by-step explanation:
The Boolean function f(a, b, c, d) = (a b c' d')(a' b' c')(a b d)(a' c) can be expressed as:
f = (a b c' d')(a' b' c')(a b d)(a' c)
This expression represents a combination of AND and NOT operators on the variables a, b, c, and d. Each term within parentheses represents a separate condition that must be met for the overall function to evaluate to true.
