i f y o u m e a n i / i^{2} = - 1 w e h a v e i^{i} = e^{i l n (i)}

a n d l n (i) m e a n t h e p r i c i p a l d e t e r m i n a t i o n o f c o m p l e x

l o g a r i t h m e b u t i = e^{i \frac{π}{2}} \Rightarrow l n (i) = \frac{i π}{2} \Rightarrow e^{i l n (i)} = e^{- \frac{π}{2}}

i^{i} = e^{- \frac{π}{2}} .
