Question

How can you write and evaluate an nth root of a number?

Answer 1

Let's say you wanted to find the cube root of 8

You write it on your paper like this:
`\sqrt[3]{8}`

In your calculator, you'd type this in: 8^(1/3)

The exponent of 1/3 corresponds to a cube root.

In general, the exponent of 1/n is for the nth root

The connection is
`\sqrt[n]{\text{x}} = \text{x}^(1/n)`
