A common log is a logarithm with base 10, i.e., log 10 = log. A natural log is a logarithm with base e, i.e., log e = ln. Logarithms are used to do the most difficult calculations of multiplication and division .

The key for the natural log is labeled “e” or “ln” while that of the common logarithm is labeled “log”. Now, let’s check our understanding of the lesson by attempting a few problems of natural and common logarithms. Example 1. Solve for x if, 6 x + 2 = 21. Solution. Express both sides in common logarithm. log 6 x + 2 = log 21

Introduction to Logarithms. In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2 s to get 8. So the logarithm is 3. How to Write it. We write it like this: log2(8) = 3.
