### Proof that 1 equals 2

Interesting...Following this logic any number but zero will equal 1. However, with all due my respect....the statement is erronous - if you take out the imaginary number and find a proof...now this will be a real proof!

### Proof that 1 equals 2

the usual alws for exponents don't hold with complex numbers - it has to do with selecting an analytic branch for the complex logarithm... basically you are saying that two different branches of the complex log are the same... when they are not.

QuoteOriginally posted by: genkiWe can similarly 'show' that e=1 without the use of log:e=e^1=e^{1}=e^{(2pi*i)/(2pi*i)}={e^(2pi*i)}^{1/(2pi*i)}=1^{1/(2pi*i)}=1.
