We read a logarithmic expression as, “The logarithm with base b of x is equal to y,” or, simplified, “log base b of x is y.” We can also say, “ b raised to the power of y is x ,” because logs are exponents.... Specifically, the logarithmic expression log c x (read “the log base c of x”) asks the question: c to what power equals x? Thus, the equations log c x = n and c n = x mean precisely the same thing.

**Changing from Logarithmic to Exponential Form**

Specifically, the logarithmic expression log c x (read “the log base c of x”) asks the question: c to what power equals x? Thus, the equations log c x = n and c n = x mean precisely the same thing.... In this section we will discuss logarithm functions, evaluation of logarithms and their properties. We will discuss many of the basic manipulations of logarithms that commonly occur in Calculus (and higher) classes. Included is a discussion of the natural (ln(x)) and common logarithm (log(x)) as well as the change of base formula.

In the logarithmic table of base 10. suppose you need to find [math]log15. [/math] For number 15 the first 2 digit is 15 and third digit is 0 as 15 can be represented as 15.0 So, go to the row with number 15 and go to the column of number 0.

5/03/2017 · To do it this way, to say that 'x' is the power you raise 3 to to get to 81, you had to use algebra here, while with just a straight up logarithmic expression, you didn't really have to use any algebra, we didn't have to say …... In this section we will introduce logarithm functions. We give the basic properties and graphs of logarithm functions. In addition, we discuss how to evaluate some basic logarithms including the use of the change of base formula. We will also discuss the common logarithm, log(x), and the natural logarithm, ln(x).

- \[3\log x - 6\log y = \log {x^3} - \log {y^6}\] We now have a difference of two logarithms and so we can use Property 6 in reverse. When using Property 6 in reverse remember that the term from the logarithm that is subtracted off goes in the denominator of the quotient.
