1.

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

Usually abbreviated to "log".

For 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

For example 10(log10(x)) = x

And generally n(logn(x)) = x


2.

The logarithm to the base 10.
