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.
If a number has an antilog whose integer part is n, then the number has n-1 digits before the decimal point.
The answer is easy if you are familiar with scientific notation. The antilog of a number, whose integer part is n, has 10n in its scientific notation. Otherwise: the number that you want the antilog for will normally be in decimal form: consisting of an integer part, a decimal point and a fractional part. The number of integer digits in the antilog is one more than the integer part of the number being "antilogged" (exponentiated). antilog(0.1234) = 1.3286*100 = 1.3286 antilog(1.1234) = 1.3286*101 = 13.286 antilog(5.1234) = 1.3286*105 = 132860 antilog(-3.1234) = 1.3286*10-3 = 0.0013286
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.
how to find antilog(20/2) answer
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.
Raise 10 to the power of the number. The antilog of 2 is 102 = 100 The antilog of 5 is 105 = 10,000 The antilog of 'pi' is 103.1416 = 1,385.46 (rounded)
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.
Assuming working to base '10' , then Antilog 2.3909 is 10^(2.3909) = 245.9801149/ Remember for logarithms. log of a number is log(10)[number] Hence its antilog is 10^(log number).
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!
