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. Let's try and prove the change of base formula.
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. Example 2. Expand log3(7a) log3(7a) = log3(7 • a) = log37 + log3a. The answer is log37 + log3a.

Log base 2 is useful to write the exponential form with a base of 2 into logarithmic form. The number 2 0 = 1, 2 1 = 2, 2 2 = 4, 2 3 = 8, 2 4 = 16, but if we have 2 x = 25 and we need to find the value of x, then we can first write it as log base 2 or \(log_225 = x\), and find the value of x.
