These worksheets give your students a review in using logarithmic expressions to answer word problems.

#### How do you approach solving logarithm word problems? Are you stuck with math once again, and are you confused and nervous? And are word problems bugging you again? Word problems are, for sure, one of the trickiest parts of math. Just looking at the huge questions gives you goosebumps, is not that right! And the most challenging part, where you have to figure out the words from English and convert them to mathematical equations, yikes! Okay, here is the deal. It is not that difficult, really. All it requires is a little skill, concentration, attention, and organization. If you are confused about how you can approach Logarithm word problems, there is no need to worry. Here is what you need to do: Take a look at the question. Now, read it carefully, entirely. Ensure that you read the question with full concentration and do not begin solving the question without reading it thoroughly, and especially not halfway. Read the question at least twice so that you know how you can start. Next, begin writing and organizing the values and numbers given to you in the question. Use the logarithms and solve!

Logarithm word problems are a constant in the study of Chemistry and Earth Science. The scale that measures how acidic or basic a substance is based on the logarithmic scale to measure the concentration of hydrogen ion in a solution. The Richter scale that quantifies the intensity of an Earthquake also involves finding the logarithmic vale of the quotient of the intensity and the movement detected. Your students will use these activity sheets to review how to use logarithmic expressions to answer word problems.
