A logarithmic function is the inverse of an exponential function, expressed as f(x) = log b x. The number b (base of the logarithm) is always positive and different from 1. Natural logarithms are a special type, with base e (approximately equal to 2.71828). This is denoted as f(x) = ln x.

The ‘log of a power’ becomes the power times log: logb(x^n) = n * logb(x). The log base b of b is 1, i.e. logb(b) = 1. Remember that understanding these basic principles about exponentials and logarithms, and how to manipulate them, is key to tackling various types of problems in mathematics.
