Final answer:
The statement about CNF being a sum of product terms is false; CNF consists of a conjunction of disjunctions of literals, unlike DNF.
Step-by-step explanation:
The statement "A boolean expression is in conjunctive normal form (CNF) if it is represented as a sum of product terms" is false. A boolean expression is actually in CNF when it is a conjunction (AND) of one or more clauses, where a clause is a disjunction (OR) of literals. In contrast, a sum of product terms describes a boolean expression in disjunctive normal form (DNF), where it is an OR of AND clauses.
To correctly describe CNF, one could say: "A boolean expression is in conjunctive normal form (CNF) if it is a product (AND) of sums (OR) terms." CNF is useful for certain types of logic solvers and is particularly suitable for algorithms used in automated theorem proving and circuit design.
