Definition of log in math
WebValue of Log10 e. The log function of e to the base 10 is denoted as “log 10 e”. According to the definition of the logarithmic function, it is observed that. Base, a = 10 and 10 x = b. Therefore, the value of log e to the base 10 as follows. Log 10 e = log 10 (2.7182818) = 0.434294482. Log10 e = 0.434294482. Where the value of e is 2.7182818. WebLogarithms or logs are a part of mathematics. They are related to exponential functions.
