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.
Antilog table gives the antilog of a positive or a negative number. Antilog is the inverse of the logarithmic function. i.e., if log x = y then x = antilog (y). i.e., if "log" moves from one side to the other side of the equation, it becomes an antilog. So
Taking log on both sides,log x = log (6.723 × 21.572)Using one of the properties of logarithms,log x = log 6.723 + log 21.572Using the log table,log x = 0.8276 + 1.334log x = 2.1616
The antilogarithm table gives the antilog of a positive or a negative number. Antilog table is used to find the anti-logarithm of a number. Antilog is a function that is the inverse of the log function.
