# How to calculate the exponential value in Python?

Let’s learn how to calculate the exponential value in Python. This knowledge can be valuable in various scientific, engineering, and mathematical applications.

## Using the Exponentiation Operator

The easiest way to calculate the exponential value in Python is to use the exponentiation operator (**) double asterisk.

```my_base = 5
my_exponent = 3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = 5
my_exponent = -3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = -5
my_exponent = 3
print ("Exponential value equals: ", my_base ** my_exponent)

my_base = -5
my_exponent = -3
print ("Exponential value equals: ", my_base ** my_exponent)
```

## Using a pow method

Alternatively, you can use the pow function from the math module.

```import math

my_base = 5
my_exponent = 3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = 5
my_exponent = -3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = -5
my_exponent = 3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))

my_base = -5
my_exponent = -3
print ("Exponential value equals: ", math.pow(my_base, my_exponent))
```

## Using an exp method

In case you would like to calculate the exponential value of Euler’s constant number you need to use exp method of math module.

```import math

my_exponent = 3
print ("Exponential value equals: ", math.exp(my_exponent))

```
