log is used to find "a" square calculation
take the number as 1.75
assume it as 175
take the first two digits on the coloumn of numbers 10,11......
take the digit 5 on the horizontal line starting from 0,1.......
if there is another number next to 5 then find it from the corresponding value of that number.subtract one from 1 from th number of digits. in the case of 1.75 =1-1=0 note; this should be doneonly after the log value.
in antilog the decimal part is alone required. if it is 0.4350 take .43 on the vertical side and 5 on the horizontal side. add one to the nmber not to the numberof digits.

How to convert log values into antilog values?
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
What is the cubic root of 13.74?
antilog( (log 13.74)/3)
How to find antilog negative number?
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.
What is the difference between an anti-log and an exponential?
let x and y be two numbers ex = y log y = x antilog x = y
How do you get decimal point in anti-log?
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
How do you see anti log without anti log table?
Without antilog tables or a scientific calculator you cannot. Antilog(x) is usually 10x or ex and that is not simple to calculate.
What is the antilog of 2.3909?
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).

What is the cube root of 45?
Antilog ((log 45)/3)
What is the cubic root of 13.74?
antilog( (log 13.74)/3)
How do you find antilog of 24.6992?
log(24.6992) = 1.392682887 Now the anti-log. 101.392682887 = 24.6992 ---------------
How do you find cube of a number using log?
If log(x) = y then log(x3) = 3*log(x) = 3*y so that x3 = antilog(3*y) So, to find the cibe of x 1) find log x 2) multiply it by 3 3) take the antilog of the result.
If log 12 equals 1.07918 then the anti-log equals?
log(10) 12 = 1.07918 Then the antilog is 12 = 10^(1.07918) You must specify the base to which to logarithm is functioning. Different log bases will give different answers.
How to find antilog of number?
Formula- Antilog of x is equal to 10xGoing along with the following example, 102.6992 = 500.265 --------------------------------------------------------Find the antilog of 2.6992 . The number before the decimal point is 2, so the decimal point will be after the first 3 digits. From the antilog table, read off the row for .69 and column of 9; the number given in the table is 5000. The mean difference in the same row and under the column 2 is 2. To get the inverse of mantissa add 5000 + 2 = 5002. Now place a decimal point after the first 3 digits and you get the number 500.2 Thus antilog 2.6992 = 500.2 Example 2 : Find the antilog of 1.0913. The number before the decimal point is 1, the number of zeroes after the decimal point is zero. From the antilog table, read off the row for .09 and column of 1; the number given in the table is 1233. The mean difference in the same row and under the column 3 is 1. To get the inverse of mantissa add 1233 + 1 = 1234. Now place a decimal point before the first digit and you get the number 0.1234. 5.ApplicationsWe will now see how logarithms and antilogarithms of numbers are useful for calculations which are complicated or have very large/small numbers. Example 1 : Find 80.92 * 19.45. Let x = 80.92 * 19.45 Use the log function on both the sides. log x = log (80.92 * 19.45) log (80.92 * 19.45) = log 80.92 + log 19.45 ( from the laws of logarithms) From the log tables we get log 80.92 = 1.9080, log 19.45 = 1.2889 Thus log (80.92 * 19.45) = 1.9080 + 1.2889 = 3.1969 log x = 3.1969 Now use antilog functions on both the sides. x = antilog 3.196 From the antilog tables we see that the antilog of 3.1969 is 1573.0. Example 2 : Find (0.00541 * 4.39)71.35 Let x = (0.00541 * 4.39)71.35 Take log functions on both the sides. log x = log ( (0.00541 * 4.39) ) ñ log (71.25) ( from the laws of logarithms) First term on the RHS : log ( (0.00541 * 4.39) ) = log (0.00541 * 4.39 )‡ = 1/2 log (0.00541) + 1/2 log (4.39) log (0.00541) = - 2.2668 ‡ log (0.00541) = - 1.1334 log (4.39) = 0.6423 ‡ log (4.39) = 0.3212 Thus the first term on the RHS : -0.8122 The second term on the RHS : log (71.25) = 1.8527 _Thus log x = - 2.6649; in terms of bar, this can be written as 3.3351. Now take the antilog functions on both the sides, we get x = 0.002163.
How do you use logarithm tables for division?
Suppose you want to divide x by y Find log(x) and log(y) to any base b (usually 10 or e) Calculate z = log(x) - log(y) Look up the antilog of z (or find the number whose log is z). x/y = antilog(z)
How to find antilog negative number?

How do you calculate an antilog on a casio fx-115ES?
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
