$$e^{\pi i}+1=0$$

$$e^{\pi i}=-1$$

$$\pi i = ln(-1)$$<---------- ?????

Is there any mistakes in this?

Sorry Max, this is a well known fact!

However, it's always more interesting to discover these things for yourself than just being told by someone else!  Well done!

There is no fault to your logic :)

I do agree though, it is interesting :)

The left hand side is imaginary, so why would you expect the right hand side to be real ?
