Cube Root Calculation
Online calculator to calculate the cube root for both positive and negative numbers.
A cube root is the number that is multiplies by itself three times in order to form a cubic value.
This is also called the perfect cube, means that an integer that has an integer value as the cube root.
Where, N= Number
For the example : 5 x 5 x 5 = 125.
The cube root of 125 (3√125) is 5.This is also called the perfect cube, means that an integer that has an integer value as the cube root.
Formula:
Cube Root = ∛ NWhere, N= Number

Some important points
The Greek mathematician Hero of Alexandria devised a method for calculating cube roots in the 1st century CE
The Indian mathematician and astronomer Aryabhata also gave a method for finding the cube root of numbers having many digits in 499 CE.
The cube of a negative number will also be a negative number.
The symbol of Cube Root = ∛
The cube root of a negative number's will always be negative. Cubing a number means raising it to the 3rd power that is odd, therefore cube roots of negative numbers will be negative.
