Logarithms are the inverse of exponential functions. The expression log𝑏𝑥 is read “log base b of x”. b is the base of the log, and it has the restrictions: 𝑏>0 and 𝑏≠1. x is called the argument of the log. Logs can have any base, but frequently-used bases are 10 and e. Common Log has base 10. If the log has no
That concludes our introduction to logarithms. In the lessons to follow we will learn some important properties of logarithms. One of these properties will give us a very important tool which we need to solve exponential equations. Until then let’s practice with the basic themes of this lesson.
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. John Napier introduced the concept of Logarithms in the 17th century.
In this unit you will examine the definition and inverse relationship with the exponential function, practice the laws of logarithms, solve logarithmic equations, and explore a more efficient method for solving equations using the “Change of Base” formula for logarithms.
While we have introduced logarithms with a changeable base, there are two main bases that are found on most scienti c calculators, and are used more than others. Firstly, the common logarithm, most commonly written as just log(x).
