What is inverse of log?
We know that the inverse of a log function is an exponential. So, we know that the inverse of f(x) = log subb(x) is f^-1(y) = b^y. If the base is e and we are dealing with the natural log, then the inverse of f(x) = ln(x) is f^-1(y) = e^y.
What is log to the base 1?
Since log(1) = 0. Then log of a with base 1 would be dividing by zero which is undefined. 1 raised to any power is equal to 1.
What are the log rules?
The rules apply for any logarithm logbx, except that you have to replace any occurence of e with the new base b. The natural log was defined by equations (1) and (2).
Basic rules for logarithms.
| Rule or special case | Formula |
|---|---|
| Quotient | ln(x/y)=ln(x)−ln(y) |
| Log of power | ln(xy)=yln(x) |
| Log of e | ln(e)=1 |
| Log of one | ln(1)=0 |
