Explain pow(x, y) in python with example.

1.	Explain pow(x, y) in python with example.
Answer» Description : The method pow() returns returns the value of x to the power of y. Syntax: Following is the syntax for pow() method import math math.pow(x,y) 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, y—This is also a numeric expression. Return Value : This method returns value of x to the power of y. Example: The following example shows the usage of pow() method. # !/usr/bin/python import math # This will import math module print “math.pow(100, 2): “, math.pow(100,2) print “math.pow(100,-2): “, math.pow(100,-2) print “math.pow(2,4): “, math.pow(2,4) print “math.pow(3, 0): “, math.pow(3,0) This will produce the following result: math.pow(100, 2) :10000.0 math.pow(100,-2): O.OOOl math.pow(2, 4): 16.0 math.pow(3,0): 1.0

Description : The method pow() returns returns the value of x to the power of y.

Syntax: Following is the syntax for pow() method import math math.pow(x,y)

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, y—This is also a numeric expression.

Return Value : This method returns value of x to the power of y.

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

# !/usr/bin/python

import math # This will import math module

print “math.pow(100, 2): “,

math.pow(100,2)

print “math.pow(100,-2): “,

math.pow(100,-2)

print “math.pow(2,4): “,

math.pow(2,4)

print “math.pow(3, 0): “,

math.pow(3,0)

This will produce the following result:

math.pow(100, 2) :10000.0

math.pow(100,-2): O.OOOl

math.pow(2, 4): 16.0 math.pow(3,0): 1.0
