Pardon? Messed with Maths!

Can you find an error to this syllogism?
e^iπ=-1 Αs far, as good..
(lots may not be aware of this, but you can find this equation to a maths book or an encyclopedia....)
(e^iπ)²=-1² Squaring.. Legitimate maths as far..
e^2iπ=1 Just enclosing the squares in the numbers...
2iπ=ln1 Getting rid of Napier's number using the "ln"
2iπ=0 (!!!!!) And what's more:
i=0 2 and π are just numbers..!
Well, if not.. then what the heck? Does i equals zero?
Is that possible?
