A logarithm answers the question: “To what exponent do I need to raise a given base to get a certain number?” For instance, if we have 2 3, the logarithmic equivalent would be log 2 (8) = 3. In this case, the logarithm tells us that we need to raise 2 to the power of 3 to get 8. The general form of a logarithm is written as: log b (y) = x
Scroll down to see all of our available logarithm worksheets. We have a pretty solid collection for you that includes. You will be asked to calculate the value of logs, understand how expressions fit into the mix and best of all are our logarithm word problems.
Definition 1: The logarithm with base 10 is called the _____ logarithm. o The base does not need to be shown when writing a common logarithm. o “log x” is understood to mean “log 10 x”. (You do not have to write the 10). o The LOG key on your calculator gives base 10 logarithms. Ex 1: Evaluate log 8 ylog 10
What is Logarithm? When you are performing complex mathematical problems, there are a few functions that are mandatory to understand for easier calculations. One of those functions is the logarithm. A logarithm is a power to which any number needs to be raised in order to get another number.
Simplify each of the following logarithmic expressions, giving the final answer as a single fraction. a) log 24 b) log 84 c) log 2 24 ( ) d) 5 1 log 125 1 2, 3 2, 3 4, 3 2 −
log . . . = 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.
