## e calculator

This e power calculator helps to calculate the result of some value x raised to e aka Euler’s number as power.

## What is e?

The letter “e” in mathematics is known as Euler’s number. It is an irrational number.  The value of `e is 2.718281828459045` and so on.

This number is used greatly in math and physics in different equations.

## How to calculate e to the x?

To calculate e raised to the power x, you first need to round off Euler’s number according to your choice. After that, use the same process as the one used in calculating exponents

Example:

Determine the value of e power 5.

Solution:

As,

`x = 5`

Step 1: Round off the value of e.

In this example, let’s use 7 decimal places.

`2.7182818`

Step 2: Multiply this value by itself x number of times.

Here, we will multiply the value of e five times.

e5 = 2.7182818 × 2.7182818 × 2.7182818 × 2.7182818 × 2.7182818

`e5 = 148.41`
