Properties of Exponents and Logarithms

ln x is called the natural logarithm and is used to represent log e x , where the irrational number e 2 : 71828. Therefore, ln x = y if and only if e y = x . Most calculators can directly compute logs base 10 and the natural log. orF any other base it is necessary to use the change of base formula: log b a = ln a ln b or log 10 a log 10 b.

INTRODUCTION TO INFORMATION THEORY

measure is roughly speaking the logarithm of the number of typical values that the variable can take, as the following examples show. Example 1.3 A fair coin has two values with equal probability. Its entropy is 1 bit. Example 1.4 Imagine throwing Mfair coins: the number of all possible out-comes is 2M. The entropy equals Mbits.

base of your logarithm, and b is the base you would like to have instead. log a (x) = log b (x) log b (a) Cancellation Properties of Logarithms These rules are used to solve for x when x is an exponent or is trapped inside a logarithm. Notice that these rules work for any base. log a (a x) = x (this allows you to solve for x whenever it is in ...
