In days before electronic calculators, logarithms were used for carrying out multiplications and divisions. In those days, this was particularly important because all navigation tables, and astronomical data that they were based on, required a lot of complicated calculations.
Nowadays, those functions are easily carried out by computers. However, there are still uses in calculus, statistics, economics. If one variable is related (or correlated) with another according to some power rule, then their logarithms will have a linear relationship. And linear relationship are much easier to estimate and work with. This is particularly relevant in classical physics where the inverse square law is so wide spread. Also in biochemistry where the volume to surface-area of cells is related to the 3/2 power.
A simplistic example from economics: if percentage increase in total productivity is related to the percentage increase in capital, then the relationship between log(productivity) and log(capital) is linear.

Are logarithms and anti logarithms same?
No, they are opposites, just like multiplication and division are opposites.
When were logarithms developed?
Michael Stifel published his discovery of logarithms in 1544. John Napier publicly propounded the method of logarithms in 1614. For more details see related link.
What are some uses of logarithms?
Many things in nature tend to grow in an exponential fashion, meaning their growth is relative to their size at the moment. Bank investments, bacterial colonies, and numerous examples in physics follow such models. In order to remove the exponents and get linear equations which are far more manageable, logarithms can be used.
When does Exponents used to solve a math problem?

Why were logarithms invented?
Logarithms were invented by John Napier who was a mathematician. He invented other things too, so there was no reason why he couldn't invent the logarithms. Logarithms were invented so people could take short cuts to multiplications! :)
When did John Napier invent logarithms?
In 1614, John Napier published his invention of logarithms.
Are logarithms and anti logarithms same?
No, they are opposites, just like multiplication and division are opposites.
What significance and advantage did the invention of logarithm bring to man?
The significance of logarithms to man is: Logarithmic functions are used in many fields mainly based in many courses offered by some schools.Logarithmic functions are usually used by some students who study on engineering and in their lines of interests that tackles about logarithmic problems.Engineers specially uses this during the construction and the measurement of their projects.Without the use of logarithms today,Sciences and other fields that have connection on Science that uses logarithms are meant to be useless where such tool is missing on it. Logarithms greatly affects the school based sciences and even international findings. -more answers on mathwikies. -Professor of Norwalk - La Mirada Unified School District
Why do pupils have to learn about logarithm so much if it has become almost unnecessary in practice since everybody has and uses modern calculators?
Nobody needs to learn how to use logarithms to perform arithmetic, however, logarithms are still a significant part of mathematical theory, and you can do many other things with them, aside from arithmetic.
When were logarithms developed?
Michael Stifel published his discovery of logarithms in 1544. John Napier publicly propounded the method of logarithms in 1614. For more details see related link.
How are logarithms used in electrical engineering?
Electrical engineers use logarithms to work on signal Decay.
Who was it invented?
John Napier of Merchiston. A Scotsman developed logarithms. He published his work in 1614. NB Modern calculators have logarithmic tables integrated into them. However, to multiply say . 45 X 2.67. It can be done by Long Multiplication. However, using 'log tables', it becomes an addition. Hence log 123.45 = 2.09149 log 2.67 = 0.42651 Add the logs. 2.09149 + 0.42651 = 2.518 Anti log ( 2.518) = 329.60971 This compares favourably with direct multiplication at 329.6115 You can use logs for division too!!! Except that you subtract the log values. NB The is a book of Log. Tables. ; 'Castle's Four Figure Tables'. You can also change the log. bases using the formula log(a) b = log(c)b / log(c)a. , where the base is changed from 'a' to 'c' ; '10' to 'e' on a calculator.

What are in the logarithms table?
The logarithms of numbers from 1 to 10 in small steps, including rules for interpolation. There may also be logarithms of common trigonometric functions such as sine and cosine.The logarithms will often be to base 10 and natural logs (base e). The tables will also contain antilogarithms.
