# Inverse Log Calculator

Enter a number and a base into the calculator. The calculator will display the inverse log of the number and base entered. The base of the natural log is equal to e=2.71828. The standard base for log is base 10.

## Inverse Log Formula

The following formula is used to calculate the inverse log of a number and base.

x = logb-1(y) = b y

• Where x is the value you are calculating
• b is the base
• and y is the number to take the log of

How to calculate the inverse log

1. First, determine the base

Logarithmic functions all require a base number. This is typically represented as b in the equation above. The natural log (ln) as a base of e = 2.718…

2. Next, determine the value y

Determine the number you wish to take the inverse log of.

3. Calculate the inverse log

Calculate the inverse log of y using the formula above.
