What is the difference between log and antilog?? |
|
Answer» The anti-logarithm of a number is the inverse process of finding the logarithms of the same number. If x is the logarithm of a number y with a given base b, then y is the anti-logarithm of (antilog) of x to the base b. LogarithmsA logarithm of a number is the power to which a given base must be raised to obtain that number. The power is sometimes called the exponent. In other words, if by = x then y is the logarithm of x to base b. For example, if 24 = 16, then 4 is the logarithm of 16 with the base as 2. We can write it as 4 = log 2 = 16. |
