Cube Calculator (x³ | x cubed)

What is x³?

In mathematics, x³ is the cube of x, also written as x raised to the power of 3. This means you multiply x by itself 3 times:

x³ = x * x * x

For example, if x = 2, then:

x³ = 2 * 2 * 2 = 8

Therefore, x³ represents the product of multiplying x by itself 3 times. It is a term in a cubic polynomial and can be visualized as a parabola in Cartesian coordinates.

Key Aspects of x³

Here are some key aspects of x³:

1. Multiplication: It represents the cube of x, which means multiplying x by itself three times: x³ = x * x * x.

2. Exponent: The 3 in x³ is the exponent, indicating the number of times x is multiplied by itself.

3. Value: The value of x³ depends on the value of x. For example, if x = 2, then x³ = 8.
