Question

My teacher never taught me how to find the index. i watched tons of videos but still don’t know how to solve this problem

Answer 1

Recall that:

The index is the number outside the sqrt. (it’s 2 if it does not have a number).

The radical is the sqrt symbol.

The radicand is the number inside the sqrt symbol.

The given radical is:

`\sqrt[4]{8}`

Therefore, from the above definitions, the index is 4
