# Python math.pow() Method

Python `math.pow()` method is an efficient way of calculating the value of the number `x` raised to the power of another number, `y`.

## Syntax of Python `math.pow()` Method

``````math.pow(x,y)
``````

### Parameters

Parameters Description
`x` Any positive or negative number representing the base.
`y` Any positive or negative number representing the power.

### Return

This method returns a float/integer value depending on the input parameters. It returns x^y.

## Example 1: Use the `math.pow()` Method in Python

``````import math

x=2

y=4

value=math.pow(x, y)

print(f"{x} raised to the power {y} is {value}.")

x=6

y=-3

value=math.pow(x, y)

print(f"{x} raised to the power {y} is {value}.")

x=math.inf

y=4

value=math.pow(x, y)

print(f"{x} raised to the power {y} is {value}.")

x=1

y=math.inf

value=math.pow(x, y)

print(f"{x} raised to the power {y} is {value}.")
``````

Output:

``````2 raised to the power 4 is 16.0.
6 raised to the power -3 is 0.004629629629629629.
inf raised to the power 4 is inf.
1 raised to the power inf is 1.0.
``````

Note that the arguments can be in integers or floats. The values may be either positive or negative.

## Example 2: Shorter Syntax of the `math.pow()` Method

``````import math

print("2 raised to the power 5 is ", math.pow(2,5))
``````

Output:

``````2 raised to the power 5 is  32.0
``````

These methods are used in mathematical computations related to geometry and have a certain application in astronomical computations.

## Example 3: Calculate the Square and Square Root of a Number Using the `math.pow()` Method

``````import math

x=4

y=2

z=1/2

value=math.pow(x, y)

print(f"The square of {x} is {value}.")

value=math.pow(x, z)

print(f"The square root of {x} is {value}.")
``````

Output:

``````The square of 4 is 16.0.
The square root of 4 is 2.0.
``````

Adjusting the value of the second parameter of the `math.pow()` method can help us to calculate the roots and powers of any number `x`.

## Example 4: Errors When Using the `math.pow()` Method

``````import math

x=-2 # x is negative

y=1.5 # y is not an integer

value=math.pow(x, y)

print(f"The square of {x} is {value}.")

x=4

y=1+4j # complex number

value=math.pow(x, y)

print(f"The square of {x} is {value}.")

x=-2

y="hello" # string

value=math.pow(x, y)

print(f"The square of {x} is {value}.")
``````

Output:

``````Traceback (most recent call last):
File "main.py", line 7, in <module>
value=math.pow(x, y)
ValueError: math domain error
Traceback (most recent call last):
File "main.py", line 15, in <module>

TypeError: can't convert complex to float
Traceback (most recent call last):
File "main.py", line 24, in <module>
value=math.pow(x, y)
TypeError: must be real number, not str
``````

Note that if both the parameters of `math.pow()` are finite numbers and `x` is negative but `y` is not an integer, then a `ValueError` exception is thrown.
