# Exponential Equation Calculator

The **exponent **of a number is defined as how many times the number is multiplied by itself.

## What is an Exponential Equation Calculator?

'Exponential Equation Calculator' is an online tool that helps to calculate the variable value for the given exponential equation. Online Exponential Equation Calculator helps you to calculate the variable value for the given exponential equation in a few seconds.

## How to Use Exponential Equation Calculator?

Please follow the steps below on how to use the calculator:

**Step 1:**Enter the values in the given input boxes.**Step 2:**Click on the**"Solve"**button to find the variable value for the given exponential equation.**Step 3:**Click on the**"Reset"**button to clear the fields and enter the new values.

## How to Find Exponential Equation?

**Exponential equations** are defined as the type of equations that contain a base and variables as the exponent. 3^{x} =27 and (−2)^{4x+ 1 }= 64 are the examples of exponential equations.

There are different types of exponential equations. Some have equal bases on both sides of the equation and some involve different bases. We also need to use logarithms to solve the equations.

Let us see an example to understand briefly.

**Solved Example:**

Solve the value of x when 5^{x} = 100

**Solution:**

Taking log on both sides

log 5^{x} = log_{10}100

x × log_{10}5 = log_{10}^{100}

x × 0.6989 = 2

x = 2/0.6989

x = 2.8616

Therefore, the value of x is 2.8616

Similarly, you can try the calculator to solve the value of the variable for given exponential equations:

- 10
^{x}= 200 - 5
^{x }= 10^{15}
