There is no simple method to calculate logarithms. The traditional way to find a log of a number was to look it up in a table. You then had to add for the power of ten in the top digit. For the number 2000, you would look up 2.00 in the table and get the result .30103. Then, because 2000 is 2.00 x 103, you would add 3 to the answer and get 3.30103.
Luckily, that isn't usually necessary anymore. Nearly all good calculators have a log button. You can also do them with the Google search bar (hardly anyone seems to know this). Just type in log(2000) and Google instantly gives the answer:
log(2 000) = 3.30103

Do all logarithms require a base of 10?
No. The so-called "natural" logarithms have a base of ' e ', and you can find the log of any positive number to any base you like.
How do you find the square root of a number that is not perfect square number?
The simplest way to do it is to use Logarithms, from a book of Logarithmic Tables and Anti-logarithms. You simply look up the Logarithm of your quantity, then divide that quantity by 2 , and then look up its Anti-logarithm. that will give you the answer.
Why are logarithms called logarithms?
== Logarithm== From the American Heritage Dictionary: New Latin logarithmus : Greek logos, reason, proportion, and arithmos, number
What is the natural logarithms in mathematics?
Natural logarithms are logarithms to base e, where e is the transcendental number which is roughly equal to 2.71828. One of its properties is that the slope (derivative) of the graph of ex at any point is also ex.

Why we always take base 10 in logarithm?
Actually we don't. Any number greater than 1 can be used; it need not even be a whole number. In computer science, the number 2 is often used as a base; in advanced math, the number "e" is often used - this number is approximately 2.71828..., and for theoretical reasons it is considered to be the most "natural" base for logarithms. In fact, the logarithms in base "e" are called "natural logarithms".
What does the logarithm of a decimal number tell you about a number?
Near enough the exact value of the number. Logarithms, for positive numbers, have are invertible.

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! :)
