Index of the Radical
In the radical notation , the number is called the index of the radical. The index specifies which root is being taken — it tells you the power to which some number must be raised to produce the radicand .
- For a square root, the index is , but by convention it is not written: means .
- For a cube root, the index is : .
- For a fourth root, the index is : .
- For a fifth root, the index is : .
The index must be a positive integer greater than or equal to . Together with the radicand (the expression under the radical sign), the index completely determines the value of a radical expression.
