## What does Radicand mean in math?

Mathwords: Radicand. The number under the ( radical ) symbol. That is, a number which is having its square root taken (or cube root, 4th root, 5th root, nth root, etc.). For example, 3 is the radicand in.

The radicand is the number found inside a radical symbol, and it’s the number you want to find the root of. It could be a square root, cube root or other root, which will be defined by the subscript found outside and just before the radical symbol.

## What is the index and Radicand?

The radicand is the number we take the root of. The index is the value of the root.
