What is Prenex Normal Form (PNF). Write the steps to transform a Well-Formed Formula (WFF) into PNF. Transform Ɐx(Q(x) →(ⱻx) R(x, y)).

Prenex Normal Form (PNF) is a standard form used in first-order logic to simplify quantified logical formulas. The primary aim of transforming a formula into PNF is to make it easier to manipulate and analyze. PNF ensures that quantifiers appear at the beginning of the formula, followed by a quantifier-free part. This form facilitates various operations such as substitution, unification, and resolution in automated theorem proving and artificial intelligence systems.
