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.
