Steps to Find the Inverse of a Logarithm. STEP 1: Replace the function notation f ( x ) f\left( x \right) f(x) by y. STEP 2: Switch the roles of x and y. STEP 3: Isolate the log expression on one side (left or right) of the equation.
How do you find the inverse of an exponential function in Excel?
Natural logarithm number works exactly the opposite of exponential function. This function is the inverse of the EXP function in excel where =EXP (1) is equal to 2.718282 and =LN (2.718282) is equal to 1.
What is antilog formula?
Antilog Definition: The Antilog which is also known as “Anti- Logarithms”, of a number is the inverse technique of finding the logarithm of the same number. Consider, if x is the logarithm of a number y with base b, then we can say y is the antilog of x to the base b. It is defined by. If logb y = x Then, y = antilog x.
What is inverse log on calculator?
FINDING ANTILOGARITHMS (also called Inverse Logarithm) This is called finding the antilogarithm or inverse logarithm of the number. To do this using most simple scientific calculators, enter the number, press the inverse (inv) or shift button, then. press the log (or ln) button.

What is the inverse of LOG10 in Excel?
An antilog in Excel is technically defined as the inverse of the LOG10 function. The LOG10 function means the logarithm in base 10 of a number. Given that definition, the antilog, or inverse log, of any number is simply 10 raised to that number.

What’s the inverse of a log?
exponential
Some functions in math have a known inverse function. The log function is one of these functions. We know that the inverse of a log function is an exponential. So, we know that the inverse of f(x) = log subb(x) is f^-1(y) = b^y.
