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 third power = X^3 = (X)(X)(X)

X cubed minus x cubed?
x^3 - x^3 = 0 Remember , whilst 'x' is an unknown value, that unkonwn is a fixed value. As a numerical example 3^(3) - 3^(3) = 27 - 27 = 0 The '3' is 'x' in this case
X cubed multiplied by x cubed?
x to the power of 6.
What is 2x cubed minus 50x?
Totally dependent on the value of x eg if x = 1 then answer is -48 If x = 10 then answer is 1500... If x = -5 answer is 0
How do you Convert 243 cm cubed to m cubed?
1 cm cubed = 1 cm X 1 cm X 1 cm 1 cm = .01 m, so 1 cm cubed = .01 m X .01 m X .01 m Therefore, 1 cm cubed = .000001 m cubed, and 243 cm cubed = 243 X .000001 = .000243 m cubed. In summary, multiply cm cubed by .000001 to get m cubed.
What is 4.6 cubed?
4.6 cubed = 4.63 = 4.6 x 4.6 x 4.6 = 97.336
What is the value of x cubed times x cubed?
it is x to the sixth power
X cubed minus x cubed?
x^3 - x^3 = 0 Remember , whilst 'x' is an unknown value, that unkonwn is a fixed value. As a numerical example 3^(3) - 3^(3) = 27 - 27 = 0 The '3' is 'x' in this case

What is the value of six cubed?
Six cubed means six to the third power or 6 x 6 x 6. That would be 216.
Find the value of 6 cubed?
6 x 6 x 6 = 216
Value of 9 cubed?
9 x 9 x 9 = 729
x cubed minus x?
X cubed - X cubed is zero.
X cubed plus y cubed equal 25?
This has infinitely many solutions. The idea is to solve the equation for one of the variables, say for "y". The solution will be in terms of "x" in this case. Then, if you assign any value to "x", you can calculate the corresponding value for "y".
What is the value of -15 cubed?
That's the same as (-15) x (-15) x (-15). "Cubed" means that the number is multiplied by itself, appearing three times as a factor.
What is 21x cubed-58x plus 21?
It's a third-degree polynomial in 'x'. It's value depends on the value of 'x'. Every time 'x' changes, the value of the polynomial changes.
