a square root, or cubed root, or numbers like that are considered 'radical'
The square root of a number. Radical 4 is to 2, radical 9 is equal to 3, radical 16 is equal to 4, etc.
In mathematics, a radical is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.
Examples:
√25 = 5 --> because 5 x 5 = 25
∛27 = 3 --> because 3 x 3 x 3 = 27
∜16 = 2 --> because 2 x 2 x 2 x 2 = 16
Assuming you're referring to Math:
