A square root is the number that, when multiplied by itself, gives the original number. The square root of four is two because two x two equals four.
For example, the square root of 4 is 2 because 2*2=4.
Here Are Some Different Methods to Find the Square Root in Python
Python Program to calculate the square root using Exponent
# Python Program to calculate the square root using Exponent
# we are taking a number from user as input
# entered value will be converted to int from string
num = int(input("enter a number: "))
# we are using exponent (**) sign
sqrt = num ** 0.5
print("square root:", sqrt)
Output
enter a number: 16
square root: 4.0
Python Program to calculate the square root using math.sqrt() Method
# Python Program to calculate the square root using math.sqrt() Method
# importing math module here
import math
# take input number from user & convert into integer
num = int(input("enter a number:"))
sqrt = math.sqrt(num)
print("square root:" , sqrt)
Output
enter a number: 16
square root: 4.0
Python Program to calculate the square root using math.pow() Method
# Python Program to calculate the square root using math.pow() Method
# importing math module here
import math
# take input number from user & convert into integer
num = int(input("enter a number:"))
#using a predefined method pow()
sqrt = math.pow(number, 0.5)
print("square root:" , sqrt)
Output
enter a number: 16
square root: 4.0
