X (or any letter) is a variable; you can not know the initial value unless the question specifically states what it is.
It can be manipulated into varying written forms; but the X notation itself will remain a variable.
When given a variable in the form of a letter; the only thing you can typically assume is that it is different from the other letters in the equation in some way or it would likely just have the same letter used multiple times throughout. (though this is not always an accurate assumption, there are cases where different letters end up being the same number, they just were not known at the start of the equation and are thus being represented by different variable letters)
Alternate written methods:
X to the second power = X^2 = (X)(X)

What is the value of squared?
20 squared is 20 x 20 or 400.
What is x squared over x squared?
Since x represents a single number, and it is x squared over x squared, then it will be the same numbers in the numerator and the denominator, no matter what value you replace x with (as long as you replace both x's with the same number). Therefore the answer is 1, unless the value of x is 0, in which case it is undefined. eg: 5 squared / 5 squared = 1 100 squared / 100 squared = 1 Try it with your calculator.
