    You can do this in a number of ways but I would start by writing the numerator and denominator into the polar form equivalents ( e^itheta) and apply demoivres theorem to the top and bottom and simplify. Dividing two complex numbers so you take away the arguments and divide the moduli

    I got an answer:
    z = (6i - 8)/25 and z=(10/25)e^(2.5i), does anyone else have any solutions to this? I am curious now

    Yes, that is correct...except the part in bold (not sure what you did there).
