Which term describes the symbol used to indicate a root in an expression?

Explanation:
The thing being shown when you take a root is called a radical sign. The radical sign is the symbol √ (and when you have an index, like ∛, it still represents a radical). The term “radical” names the symbol and the operation of taking a root, such as a square root or an nth root. This is different from power, which refers to exponents, vertex, which is a point on a graph, and width, which isn’t a standard root-related term. For example, √16 is a radical expression showing a square root, and ∛8 is a cube root.
