WebFor a natural number N its log to the base of 2 is equal to k and is written as log2N = k l o g 2 N = k, which can be written in exponential form as 2 k = N. Let us look at an example of converting an exponential form to log base 2. An exponential number 8 k = 2492, need to be first written to the base of 2, as (2 3) k = 2492, or 2 3k = 2492. WebThis means that logarithms have similar properties to exponents. Some important properties of logarithms are given here. First, the following properties are easy to prove. logb1 = 0 logbb = 1. For example, log51 = 0 since 50 = 1. And log55 = 1 since 51 = 5. Next, we have the inverse property. logb(bx) = x blogbx = x, x > 0.
