A logarithmic function serves as the inverse of an exponential function.
Consider this fundamental logarithmic function: log(1) = 0. No matter what the base is, it stands true.
The inverse of this function, an exponential function, is a^0 = 1.
Regardless of the value assigned to the variable 'a', when it is raised to the power of 0, the result is always 1.
Given a logarithm, you can reconstruct its inverse, which is an exponential function, by starting from the base (a) and moving counterclockwise: a^0 = 1.
These are the essential logarithmic and exponential functions that you need to commit to memory.
In summary, the key logarithmic function to remember is:
👉 Log of one equals zero!
👉 Or simply, 'Log one is zero!'
