algebra precalculus - Why does this work for i2i?



I'm finding the principal value of i2i



And I know it's solved like this:




(eiπ/2)2i



ei2π



eπ



I understand the process but I don't understand for example where does the i in 2i go?



Is this some kind of a property of Euler's number? if so please explain to me.


Answer




(eiπ/2)2i=e(iπ/2)2i=ei2π.



This is just an application of the exponent laws. Don't overthink it!
