In Mathematics, the exponential value of a number is equivalent to the number being multiplied by itself a particular set of times.

The number to be multiplied by itself is called the **base** and the number of times it is to be multiplied is the **exponent**.

Python allows users to calculate the exponential value of a number in multiple ways. Let’s look at each of them in detail!

**1. ** operator**

The double asterisk, `**`

operator is a shortcut to calculate the exponential value. Let’s take a look at how this can be used in the following code:

base = 3 exponent = 4 print "Exponential Value is: ", base ** exponent

**2. pow( )**

In addition to the `**`

operator, Python has included a built-in `pow()`

function which allows users to calculate the exponential value.

The function takes as input the base and exponent and returns the corresponding value. The general syntax of the function is:

pow(base, exponent)

Look at the coding example to see how it works:

base = 3 exponent = 4 print "Exponential Value is: ", pow(base, exponent)

**3. exp( )**

The `exp()`

function in Python allows users to calculate the exponential value with the base set to **e**.

Note:

eis a Mathematical constant, with a value approximately equal to 2.71828.- The
mathlibrary must be imported for this function to be executed.

The function takes as input the exponent value. The general syntax of the function is:

math.exp(exponent)

Execute the following piece of code to see the result!

import math exponent = 4 print "Exponential Value is: ", math.exp(exponent)
