Answer 1

When we have something like:

`\sqrt[n]{x}`

It is called the n-th root of x.

Where x is called the radicand, and n is called the index.

Then the term:

`\sqrt[4]{16}`

is called the fourth root of 16.

And in this case, we can see that the index is 4, and the radicand is 16.

At the end, we have the question: what is the 4th root of 16?

this is:

`\sqrt[4]{16} = \sqrt[4]{4*4} = \sqrt[4]{2*2*2*2} = 2`

The 4th root of 16 is equal to 2.
