8X(8Y 1:R(X;Y 1) _9Y 2S(X;Y 2) _8Y 3:R.

Transform the following predicate logic formula into prenex normal form and skolem form: 8x9y(x>0!(y>0^x=y2)) is in prenex form, while 9x(x=0)^ 9y(y<0) and 8x(x>0_ 9y(y>0^x=y2)) are not in prenex form. According to step 1, we must eliminate !, which yields 8x(:(9yr(x;y) ^8y:s(x;y)) _:(9yr(x;y) ^p)) we move all negations inwards, which yields: He proves that if every formula of degree k is either satisfiable or refutable then so is every formula of degree k + 1.
