Both for logs and antilogs, the base must be specified. Once you decide on your base, you can calculate that on any scientific calculator. Use the antilog function (base 10, or base e, if that's what you need), or calculate 10 to the power -4.1 (if you want a base-10 antilog), or e to the power -4.1 (if you want a base-e antilog), or some other base to this power. In Excel, you can use the power operator. For example, for 10 to the power -4.1 (that is, the antilog, base 10), type the following in an Excel cell: =10^-4.1
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– .

1: Calculate the square root, then calculate its square root; OR 2: Take the logarithm of the number, divide it by 4 then take the antilog.
Below the <X-1> key, below the <MODE/SETUP> key, you will find log. You have to press the <SHIFT> key (upper left-most key) and then <log> key (which accesses the <10x> antilog function); then enter the number on which you want to perfom antilog; then press the <Ans> key
The antilog of the number in the display is10xThere's probably a button somewhere on the calculator that gives you 10x . Also, this terminology, and the button, are probably discussed in the tiny bookletthat comes with the calculator.
It is 1013.309 . If your pocket calculator doesn't do 10x then you use antilog tables. It's a big number. 1013 x antilog of 0.309 might be more handy.
Without antilog tables or a scientific calculator you cannot. Antilog(x) is usually 10x or ex and that is not simple to calculate.
The Texas Instrument TI86 is a great calculator for doing taxes or any finances.

If it is log to the base 10, use the calculator to find 10 to that power. If it is log to the base e, use the calculator to find e to that power. Both the above are standard functions on all scientific calculators and are easy to work out on spreadsheets. Alternatively, you can find the antilog of the absolute value and then find the reciprocal. Thus antilog(-3.5) = 1/antilog(3.5) etc.
algorithm
1.Using calculator-press the 'shift' button and then the log number to be converted. N:B:Estimate answer to 3 s.f 2.You can also fin antilog by raising the log by power 10.e.g antilog of x is 10^x
fx 991 ms ======= "SHIFT" then "log" "DIGIT" "=" :)
Besides using a calculator, there are tables of logarithms. You can find the antilog that way. See the related link.
