The anti-log is "10^x" listed above the "LOG" key on a TI-86 calculator. All you have to do to use it is press the yellow "2nd" key (this means shift) and then press the "LOG" key.

Without tables or calculators, this kinda question is hard, so if there is a non-calculator question involving logs, just chuck numbers in. I find it helpful to rearrange the log into a power problem e.g. log2(x) = 8 --------> x = 28 = 256 or log2(8) = x ----------> 2x = 8 = 3 (by observation) or logx(8) = 2 ----------> x2 = 8, x = (+/-)(root 8) = (+/-)(2root2)

You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth. But the log, itself, is not something you can calculate.You do not calculate a log!You can calculate the surface area or the volume or, if you know the species, the mass or even time for which it would burn in a hearth.

On my CASIO fx-115MS it is the "log" button you need to press the "shift" button then press log and a small "10" will appear on your calculator screen. Hope this helps...

On my calculator it is the same key as the log key, but you have to press the "Shift" key first. It is shown as 10â– .

Without antilog tables or a scientific calculator you cannot. Antilog(x) is usually 10x or ex and that is not simple to calculate.

Unless the number happens to be a straightforward power of the base of the logs, the answer is that you cannot without some access to tables or a scientific calculator. There are Maclaurin series for the log function but without a powerful calculator, you will not get far with them.

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.

It is: 10 0.2084413564 = 1.616 by using a scientific calculator

Nowadays this is done most easily with an advanced graphing calculator.

Look it up in table of logarithms or use "log" button on scientific or other calculator. You might even be able to Google it!

It depends on what calculator you are using. Often, shift log is inverse log, or natural log, but it could have other meanings. Please restate the question and specify the model number of the calculator.

You calculate a log, you do not solve a log!

It doesn't make much sense to calculate logarithms with pencil and paper - the calculations are too involved. Just multiply the two numbers, and calculate the logarithm on a scientific calculator. If you don't have one, use the Windows calculator (it has a mode for scientific calculator).

The calculator won't do it.On the calculator, the button marked 10x gives youthe inverse log of the number in the window.
