How to solve logs with bases other than 10
WebJun 24, 2024 · The log function is used to solve equations where the variable is an exponent with base 10. For example, 10 X = 100. The log operator allows us to solve for X and write an equivalent expression as log(100) = X. 10 X = 100 is the exponential form of the expression, and log(100) = X is the logarithmic form.
