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.
Find the base for the logarithm: it is likely to be 10 if you are a newcomer to logs or e (= 2.71828...) if you are more advanced. Then the antilog of x is 10x or ex.
Take the logarithm of your number, divide it by 3 then take the antilog.
First you must decide what basis you are using for logarithms. Often this will be the number 10, or the number e. (In theory, any number greater than 1 will work.) Then you just raise the base to your number. For example, the antilog (base-10) of 5 is simply 105 = 100,000. Your scientific calculator should have an antilog key.
There is no need to find the square root of a negative number for sqrt(0.6)!

To find the antilog of a negative number, you can use the formula antilog(x) = 10^x, where x is the negative number. The antilog of a negative number represents the inverse operation of finding the power of 10 that results in the negative number.
Find the base for the logarithm: it is likely to be 10 if you are a newcomer to logs or e (= 2.71828...) if you are more advanced. Then the antilog of x is 10x or ex.
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.
Take the logarithm of your number, divide it by 3 then take the antilog.
The antilog? a log is an exponent, so as an antilog just means you reapply that exponent to the correct base. Log implies base 10, so antilog means use that number as an exponent of 10. If you are using log tables, first separate the whole number part and the decimal part of the log ( they are both negative) then add -1 to the whole number part and +1 to the decimal part. (one is called the characteristic and the other is called the mantissa, but I don't remember which is which now) This creates a positive decimal that you can look up in the log table. The negative integer part becomes an exponent of 10. Put them together and you get an answer in scientific notation. Ex: find antilog of -3.5 (-3 -1) + (-.5 + 1) ==> (-4) + (+.5) look up .5 in the log tables and you get 3.1623 and the -4 becomes 10-4 Put them together by multiplying (adding logs means multiplication of antilogs) to get the final answer 3.1623 x 10-4

Well, darling, to find the antilog of a negative number using a log table, you first need to find the positive equivalent of the negative number. Add the negative number to the log base, and then look up the result in the log table to find the antilog value. Just remember, math doesn't have time for negativity, so keep it positive!
First you must decide what basis you are using for logarithms. Often this will be the number 10, or the number e. (In theory, any number greater than 1 will work.)

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
It is simply 10 to that power. Thus, antilog(231) = 10231. Could not be simpler.
