The mathematical function which is the inverse of "raising to the power of".

Often abbreviated to "log".


Example

Working with logarithms to the base 10:

log10(100) = 2

And 102 = 100


More generally, with logarithms to the base n:

logn(x) = the power which, when 'n' is raised to it = x


Example

10(log10(x)) = x

And, more generally:

n(logn(x)) = x
