$$x^2=x \times x$$

But other than that it can equal anything.  It would depend on the rest of the question.

This could be the formula for the area of a square.

If the side length is x then area = x squared units squared

This would be a formula

$$Area = x^2\\\\ If the side length is 6 cm then x=6 and\\ Area = 6^2 = 36cm^2\\\\ If the side length is 4inches then x=4 and\\ Area = 4^2 = 16inches^2\\\\ etc\\ Do you get the idea on how this might be useful?$$
