Nth root calculator

This nth root calculator will compute the nth root of any number with just the click of a button.

Guidelines to follow when using the nth root calculator to find the nth root of a number

1. Calculate the cube root of 27 (∛27):

Enter 27 in the box that says,"Enter the number you want to take the root of"

Enter 3 in the box that says, "What root do you want to take?"

The big box will show 3 as an answer. 

2. Calculate the fourth root of 625 (∜625):

Enter 625 in the box that says,"Enter the number you want to take the root of"

Enter 4 in the box that says, "What root do you want to take?"

The big box will show 5 as an answer. 

3. Calculate 6th root of 4096:

Enter 4096 in the box that says, "Enter the number you want to take the root of"

Enter 6 in the box that says, "What root do you want to take?"

The big box will show 3.99999996 as an answer. 

Key concept

Square root of a number

Square root of 4 is 2 because 2 times 2 is 4

Square root of 64 is 8 because 8 times 8 is 64

Cube root of a number

Cube root of 27 is 3 because 3 times 3 times 3 = 27

Cube root of 125 is 5 because 5 times 5 times 5 = 125

Fourth root of a number

The fourth root of 16 is 2 because 2 times 2 times 2 times 2 = 16

The fourth root of 625 is 5 because 5 times 5 times 5 times 5 = 625

Fifth root of a number

The fifth root of 243 is 3 because 3 times 3 times 3 times 3 times 3 = 243

The fifth root of 1024 is 4 because 4 times 4 times 4 times 4 times 4 = 1024

Ready for big time challenge? Just like long division, learn how to compute the square root without a calculator for any number that is not a perfect square. I promise you will not sweat too much!
