The logarithmic functions have inverse functions that happen to have specific names. Even if the log^-1 notation may found on textbooks you will not find it on claculators.
Natural Logarithms LN. The inverse function of the natural logarithm is the EXPONENTIAL noted e to the x or e^x. On calculators the two functions usually share the same physical key. For example, LN is accessed directly and e^x is accessed with

Sorry, the submit button was pressed before the end.
For example, LN is accessed directly and e^x is accessed with [2nd][LN].
For decimal logarithms (log), its inverse function is 10^x. To access it press [2nd][LOG].
