# High School Math : Expressing Radicals as Exponents

## Example Questions

### Example Question #1 : Understanding Radicals

Convert the radical to exponential notation.

Explanation:

Remember that any term outside the radical will be in the denominator of the exponent.

Since does not have any roots, we are simply raising it to the one-fourth power.

### Example Question #51 : Algebra Ii

What is the value of ?

243

2.41

9

27

3

243

Explanation:

An exponent written as a fraction can be rewritten using roots.   can be reqritten as .  The bottom number on the fraction becomes the root, and the top becomes the exponent you raise the number to. is the same as . This will give us the answer of 243.
