Take the cube root of a number using the product of cubed numbers, cuberoot(250)

The video tutorial discusses methods for simplifying square and cube roots. It begins with an explanation of prime factorization and how it applies to square roots. The tutorial then introduces a method for simplifying cube roots by identifying multiples of known cubes, such as 8, 27, 64, and 125. This method is presented as easier than prime factorization due to the limited number of cubes. The video concludes by comparing the complexity of simplifying square roots versus cube roots, emphasizing the efficiency of the cube root method.
