Here's the Solution to this Question

Let us find a counter example to the following universally quantified statement, where the domain for all variables consist of all integers:

$\forall x (x^2\leq x^3)$

Indeed, for the integer number $x=-2$ we have that $x^2=4, x^3=-8$ . Therefore, it is not true that

$x^2\leq x^3$ .
