Hi,(adsbygoogle = window.adsbygoogle || []).push({});

as I was studying complex numbers today I came across this, and I couldn't explain it:

[tex]1=e^{i0}[/tex]

[tex]1=e^{i2\Pi}[/tex]

[tex]1^{1/2}=e^{i2\Pi/2}[/tex]

[tex]1=e^{i\Pi}[/tex]

[tex]1=-1[/tex]

Where is the mistake?

Thank you very much for your help.
