How to find antilog without log table

Consider, if x is the logarithm of a number y with base b, then we can say y is the antilog of x to the base b. It is defined by. Both logarithm and antilog have their base as 2. If the logarithm and antilogarithm have their base 10, that should be mariana_sk xxx into natural logarithm and antilog by multiplying it by 2.

But yes you can find approximate values. Thanks to a bit of calculus. If you know the log values of first few prime numbers, you can get a close enough answer. All you need to do is express the number in a desirable product form composed of smaller numbers whose values you perhaps know. This will lead you to a close value still not good enough. For example given you know log5, and you want to know log , u get log 5. Since you know log5 , you can approximate log 5.

If the logarithm and antilogarithm have their base 10, that should be converted into natural logarithm and antilog by multiplying it by 2. Before finding the antilog of a number, we should know about the parts like the characteristic and mantissa part. Step 1: Separate the characteristic part and the mantissa part.

How to find antilog without log table

Antilog table is used to find the anti-logarithm of a number. Antilog is a function that is the inverse of the log function. We know that we use the log table for doing math calculations easily without using a calculator. While doing the calculations, we apply the log first for the given expression, and after simplifying we should use the antilog table to find the antilog of the result that gives the simplified result of the given expression.
