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 is the value of 0.05555 divide by 0.0008601 if use logarithms to solve the problem?
64.5855
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.
How do you find Antilogarithm of a given Logarithm?
Besides using a calculator, there are tables of logarithms. You can find the antilog that way. See the related link.
Have people improved on logarithms?
Yes. The invention of the electronic calculator made using logarithms unnecessary for many of the more common usages.

How do you find log of no?
Look it up in table of logarithms or use "log" button on scientific or other calculator. You might even be able to Google it!
How do you find standard deviation using a calculator?
The answer depends on what functions are built into your calculator. Read the calculator manual.
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.

Cosecant on calculator?
Cosecant is the reciprocal of sine. To find the cosecant of an angle using a calculator, find the sine of that angle (using the Sin button) and then divide 1 by the result.
How do you find the answer to 5 times 0.468?
Try using a calculator.
How can logarithms relate to everyday?
Before the invention of the calculator, people needed to perform math by hand. Using tables of logarithms greatly sped up the common tasks of multiplication, division, powers and roots. Today, people use devices or scales that are based on logarithms. Music volume is based on a logarithmic scale. Every time you turn the volume up, you are doing something based on logarithms. Earthquakes are based on a logarithmic scale. Every time that you hear about an earthquake on the news, the earthquake is described in reference to a scale based on logarithms. Earthquakes happen daily all over the world.
