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 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. From the given example, the characteristic part is 2, and the mantissa part is Step 2: To find a corresponding value of the mantissa part use the antilog table. Using the antilog table, find the corresponding value. Now, find the row number that starts with. Now, you get the corresponding value as Step 3: From mean difference columns find the value. Again use the same row number. Now, the value corresponding to this is 2.

Thanks to the antilog calculator, you can calculate the inverse logarithm function. Calculate the antilogarithm of any number with any arbitrary base — whether it is 10, natural antilog, or any other number. If you are unsure what the antilogarithm is, read the description below, where we explain everything step by step. The logarithm is the inverse function of exponentiation. That means the logarithm of a given number x is the exponent to which the base b must be raised to produce that number x. The ratio of logarithms is used in the logarithmic scale — a nonlinear scale used to compare a large range of values. It is widely used in many fields of science:.

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. Let us learn more about the antilog table along with what it looks like and how to use it for positive and negative numbers. We will solve examples using the antilog table for a better understanding of its usage. Antilog table gives the antilog of a positive or a negative number. Antilog is the inverse of the logarithmic function. To remember this simply, if "log" moves from one side to the other side of an equation, it becomes an antilog.

This can be referred to as the antilog formula. Here is the antilog table for the common logarithm. This is because in log, multiplication is changed to addition, and division is changed to subtraction. Method 2. Before finding the antilog of a number, we should know about the parts like the characteristic and mantissa part. Doc 26 Pages. Maths Questions. Most Upvoted Answer.
