Finding the fourth root of a number is like finding the **square root** of a number twice. Simply said, a number’s fourth root is a number that, when multiplied by itself four times, returns the original number. Use this fourth root calculator to find the ^{4}**√ **of any number.

We will use a basic example to illustrate the above definition: Let’s find the fourth root of 81.

The number 3 If we multiply four times, we get the product value of 81 (3 x 3 x 3 x 3 = 81). Hence, the number 3 is the fourth root of 81.

**How to Use Fourth Root Calculator?**

- Using this 4th root calculator, it is simple to determine the fourth root of any number.
- You only need to enter the number you want to find the fourth root of, and the calculator will show you the results immediately.

**How is the Fourth Root Calculated?**

Without a calculator, it might be difficult to find a number’s fourth root. If the numbers are big, doing this could take you minutes or hours. Therefore, in order to save time, we advise using the fourth root calculator above.

**Example**

1. Find the 4th root of 14641?

**Solution :**

To find the fourth root of the number, we have to find a number that can be multiplied four times to get the product value of 14641.

This is something like trial and error method.

**First Try : Lets take number 8**

We get, 8 x 8 x 8 x 8 = 4096.

**Second Try : Lets take number 9**

We get, 9 x 9 x 9 x 9 = 6561.

**Third Try : Lets take number 12**

We get, 12 x 12 x 12 x 12 = 20736. We are close enough…..

**Fourth Try : Lets take number 11**

We get, 11 x 11 x 11 x 11 = 14641. * Yippee Finally* the fourth root have been found.

*The square root method can also be used to calculate the fourth root of a number. In this case, you must repeat the steps twice. That is, to get the fourth root of a number, you must find the square root of the number twice. *

For instance, Using the square root method, find the fourth root of 16. In this case, the square root of 16 is 4, and the square root of 4 is 2. As a result, the fourth root of 16 is 2.
