The "Radical Symbol" is a shorthand notation which stands for the

roots of the number (or expression) in the radicand.

For example , the cube root of 8 stands for the number that can be multiplied by itself three times (cubed) to equal 8:

Since, 2 * 2 * 2 = 8, the cube root of 8 is 2.

The 3 in the expression is called the root index , and the 8 is called the radicand .
