If x and y are two irrational numbers, then xy may be rational or irrational.

Step-by-step explanation:

If y=x, then the above states that x2 may be rational or irrational if x is irrational. Indeed, if x is the irrational number 7–√, say, then x2=7, which is rational. But if x is the irrational number 2–√3, say, then x2=4–√3, which is also irrational.
