Change of Base. Sometimes we will be faced with logarithmic or exponential are not the same. Being able to change from one base to these situations. Let's have a look at the change of base functions. Change of base formula. loga x. logb x = log. a b. Note:
Log base 2 is a mathematical form of expressing any natural number as an exponential form to the base of 2. The exponential form of 2 4 = 16 can be easily represented as a log base 2 and written as \(log_2 16 = 4\).

. = logbX – logbY. logb(XY) = logbX + logbY Power Rule for Logarithms. Quotient Rule for Logarithms. Product Rule for Logarithms. The following examples show how to expand logarithmic expressions using each of the rules above. Example 1. Expand log2493 . log2493 = 3 • log249 . The answer is 3 • log249. Use the Power Rule for Logarithms.
Given that log 2 = x, log 3 = y and log 7 = z, express the following expressions in terms of x, y, and z. (1) log 12 (2) log 200. 14. (3) log (4) log 0:3. 3. (5) log 1:5 (6) log 10:5 6000. (7) log 15 (8) log. 7.
Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
Consider the expression 16 = 24. Remember that 2 is the base, and 4 is the power. An alternative, yet equivalent, way of writing this expression is log 2 16 = 4. This is stated as ‘log to base 2 of 16 equals 4’. We see that the logarithm is the same as the power or index in the original expression.
