Find all the complex solutions of the equation

(x^4) - 16 i = 0

Answers' to this question are supposed to be written in the following format:
r[cos(degree)+i sin(degree)] . . .

(i.e. Don't solve for x)

just take the last answer I gave you for this and have

$e^{i\phi} = \cos(\phi) + i \sin(\phi)$
