A perfect cube is a number that can be written as the product of three identical integers. In other words, a number is a perfect cube if it is the cube of an integer.
|Example||Rewrite as a Product||Perfect Cube?||Explanation|
|Yes||is an integer|
|No||is not an integer|
Similarly, if a variable has an exponent that is a multiple of it is said that it is a perfect cube. This is because this condition guarantees that the variable can be rewritten as the product of three identical powers with integer exponents.
