Step-by-step explanation:

(a) There is a number whose cube is equal to 2.

(b) The square of every number is at least 0.

\large \forall x\in \mathbb{R},\;x^2\geq 0

(c) There is a number that is equal to its square.

\large \exists x \in \mathbb{R}\;|\;x^2=x

(d) Every number is less than or equal to its square.

\large \forall x\in \mathbb{R},\;x\leq x^2

(By the way, this last statement <u>is not true</u> when 0 < x < 1)
