I came across this in QM course while trying to work out the time evolution equation of a wave-packet.

$(A+iB)^{1/2}*e^{C+iD}$

*Thank you I got it: I converted A+iB to exponential form and used De Moivre theorem to find the sqrt of A+iB, and finally combined the two exponentials and worked out the conjugate.*

Great work!
