how do I calculate the inverse of a LOG? Is is the exponent?

Answer 1

The inverse of a Natural Log (ln x) is e^x and the inverse of a base 10 log (log x) is 10^x

Answer 2

It depends on whether you want the inverse of a common log (base 10) or a natural log (base e).

For natural log, using your calculator, enter the number, then "inv" then "LN".

For common log, use "inv" then "log10" (if it exists). If not, hit 10^x (where x is the number that you want the inverse log of).
