What is the inverse of a log function?

What is the inverse of a log function?

The inverse of a logarithmic function is an exponential function.

What is log and inverse log?

Logarithms as Inverse Exponentials Throughout suppose that a>1. The function y=loga(x) is the inverse of the function y=ax. In other words, loga(ax)=xandaloga(x)=x.

What is the reverse of LOG10?

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 LOG10?

The inverse of log10 (x), denoted log(x), is 10x.

Is ln the inverse of log?

The natural log is the inverse of , a fancy term for opposite. Speaking of fancy, the Latin name is logarithmus naturali, giving the abbreviation ln.

How do you reverse a log10 transformation?

inverse function. (In general, the solution is b^x if the log is of base b . For example, if log10(y) = x then the inverse transformation is 10^x .)

What is inverse of natural log?

Definition. The exponential function, exp : R → (0,∞), is the inverse of the natural logarithm, that is, exp(x) = y ⇔ x = ln(y).

How do you find the inverse of log base 10?

Explanation: In order to eliminate the log based ten, we will need to raise both sides as the exponents using the base of ten. The ten and log based ten will cancel, leaving just the power on the left side. Change the negative exponent into a fraction on the right side.

How do I use antilog?

How to Use Antilog Table to Find Antilog of a Number?

1. Find characteristic and mantissa of the number.
2. Use the mantissa to see the corresponding number in the antilog table.
3. Place a decimal point immediately after the first digit of the number from the antilog table.
4. Multiply the above number by 10characteristic.

How do you change log back?

You can convert the log values to normal values by raising 10 to the power the log values (you want to convert). For instance if you have 0.30103 as the log value and want to get the normal value, you will have: “10^0.30103” and the result will be the normal value.

What is the inverse log 10?

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. For instance, the base-10 log of 4 is 0.60206, and the base-10 antilog of 4 is 10,000 (10 raised to the fourth power).

What is the antilog of 25?

Value of AntiLog(25)
