The base b logarithm of x is base c logarithm of x divided by the base c logarithm of b. log b ( x ) = log c ( x ) / log c ( b ) For example, in order to calculate log 2 вЂ¦, Examples of Solving Logarithmic Equations Example вЂ“ Solve: 7 7 log(2x3)log(x2)1 - - + = This problem contains only logarithms. This problem can be simplified by using Property 4 which changes the subtraction of logarithms to division. Rewrite the problem in exponential form by moving the base of the logarithm to the other side. Simplify the problem by raising 7 to the first power. Solve.

Notice that the b is the same in both the exponential function and the log function and represents the base. Here is an example of using the same set of information and expressing it as a log and Since logarithms are nothing more than exponents, these rules come from the rules of exponents. Let a be greater than 0 and not equal to 1, and let n and m be real numbers. If you want to review exponential rules in detail with examples and problems, click on Exponential RulesвЂ¦

Logarithms Formulas. 1. if n and a are positive real numbers, and a is not equal to 1, then If a x = n, then log a n = x. 2. log a n is called logarithmic function.

Logarithms University of Sheffield. Logarithmic Differentiation . We can use the properties of the logarithm, particularly the natural log, to differentiate more difficult functions, such a products with many terms, quotients of composed functions, or functions with variable or function exponents. In particular, we like these rules because the log takes a product and gives us a sum, and when it comes to taking derivatives, we like sums better than products! Similarly, a log takes a quotient.
