Describe sqrt(x) in Python with example.

1.	Describe sqrt(x) in Python with example.
Answer» Description : The method sqrt( ) returns the square root of x for x > 0. Syntax: Following is the syntax for sqrt() method import math math.sqrt(x) Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object. Parameters: x —This is a numeric expression. Return Value : This method returns square root of x for x > 0. Example: The following example shows the usage of sqrt() method. # !/usr/bin/python import math # This will import math module print “math.sqrt(100): “, math.sqrt(100) print “math.sqrt(7): “, math.sqrt(7) print “math.sqrt(math.pi): “, math.sqrt(math.pi) This will produce the following result: math.sqrt(100): 10.0 math.sqrt(7): 2.64575131106 math.sqrt(math.pi): 1.77245385091

Description : The method sqrt( ) returns the square root of x for x > 0.

Syntax: Following is the syntax for sqrt() method

import math

math.sqrt(x)

Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object.

Parameters: x —This is a numeric expression.

Return Value : This method returns square root of x for x > 0.

Example: The following example shows the usage of sqrt() method.

# !/usr/bin/python

import math # This will import math module print “math.sqrt(100): “,

math.sqrt(100)

print “math.sqrt(7): “,

math.sqrt(7)

print “math.sqrt(math.pi): “, math.sqrt(math.pi)

This will produce the following result:

math.sqrt(100): 10.0

math.sqrt(7): 2.64575131106

math.sqrt(math.pi): 1.77245385091
