A logarithm is the inverse function of an exponential function. Making the subject of gives. This is pronounced "log base a of b ". This is the definition of a logarithm. The number is called the base of the logarithm. If no base is given, it means the base number is 10. means.
Logarithms. An old logarithm table and modern calculator. Logarithms come in the form \ ( {\log _a}x\). We say this as 'log to the base \ (a\) of \ (x\). But what does \ ( {\log _a}x\) mean?
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.
In this article, we are going to learn the definition of logarithms, two types of logarithms such as common logarithm and natural logarithm, and different properties of logarithms with many solved examples.
