If you are using a scientific calculator you will have a key labelled "log". To find the logarithm (to base 10) of a number, simply enter "log" followed by the number that you want to log.
If you want a natural logarithm - log to the base e - use the "ln" key instead.
If you haven't got a scientific calculator, use the one on your computer.

What are logarithm tables used for?
Logarithm tables help you work with logarithms without using a calculator. Calculating a logarithm can be a long process. A table eliminates the need to perform extra math. If you need a specific logarithm, you simply look it up. The calculator was invented in the 1970's. Before that, people used slide rules or tables of logarithms. Using the tables of logarithms, you could perform multiplication, division, find roots or powers - and do all of that fairly easily.
What is the advantage of using logarithms?
Logarithms turn multiplication into addition, which is much faster. The same applies for division, except that the logs are subtracted. Using logarithms, finding roots or powers is easy. For example, the square root of a number can be found using 1/2 times the logarithm (plus one more step). Finding square roots is something that happens often in algebra. If you did not have a calculator, square roots would be hard without logarithms.
What is log base 4 of 27?
You can calculate that on any scientific calculator - like the calculator on Windows (if you change the options, to display as a scientific calculator). Log base 4 of 27 is the same as log 27 / log 4. You can use logarithms in any base to calculate that - just use the same base for both logarithms.
Is there an easy way to work out 30 to the power of 6 without a calculator?
Logarithms, for which you would need tables.
