![1. Let N =
x ≤ y².
{1,2,3,4,...} be the familiar set of natural numbers. Let P(x, y) be the predicate that
[General hint: since “P(x, y)" means exactly the same thing as "x <y2" in this problem, go ahead and
rewrite P(x, y) as x ≤ y² — or P(a, b) as a ≤ b², or P(A) as <A², or whatever any time you
think it might make things easier for you to look at or think about.]
