Python Program - Cube Root of a Number
If a number is multiplied by itself two times (n*n*n), the final number will be the cube of that number and finding the cube root of a number is inverse operation of cubing the number. If x is the cube root of y, it can be expressed as below:
Alternatively, it can also be expressed as:
x3 = y
Example: Using exponential (**) operator
The exponential (**) operator of Python can be used to calculate the cube root of a number. Consider the following example.
x = 64 y = 125 x1 = x**(1/3) y1 = y**(1/3) print("Cube root of", x, "is",x1) print("Cube root of", y, "is",y1)
The above code will give the following output:
Cube root of 64 is 4.0 Cube root of 125 is 5.0
Example: Using pow() method of math Module
The pow() method of math module can also be used to calculate cube root of a number.
import math x = 64 y = 125 x1 = math.pow(x, 1/3) y1 = math.pow(y, 1/3) print("Cube root of", x, "is",x1) print("Cube root of", y, "is",y1)
The above code will give the following output:
Cube root of 16 is 4.0 Cube root of 25 is 5.0
