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

**and so on.**

*2.718281828459045*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

**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.**

*x,**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.

*e ^{5 }= 2.7182818 × 2.7182818 × 2.7182818 × 2.7182818 × 2.7182818*

*e ^{5 }= 148.41*
