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.
