It won't be an integer.

Perfect cubes are the only numbers that have cube roots that are integers, since each integer corresponds to a perfect cube. But if you look at a list of integers and their cubes...

...there are a lot of numbers in between each integer's cube. Each of those numbers (for example, ) have a cube root, but the cube root will be between integers (so 's cube root will be between  and ).
