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 the 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
Inverse Log Definition
An inverse log is defined as the anti-log of a log function raised to a negative value.
Inverse Log Example
How to calculate the inverse log?
- 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…
- Next, determine the value y
Determine the number you wish to take the inverse log of.
- Calculate the inverse log
Calculate the inverse log of y using the formula above.
