i am to find the 4th roots of -16(adsbygoogle = window.adsbygoogle || []).push({});

[tex](-16)^{1/4}=2i^{1/4}[/tex]

[tex]i=e^{i \pi/2}[/tex]

[tex]i^{1/4}=e^{i \pi/8}[/tex]

[tex](-16)^{1/4}=2e^{i \pi/8}[/tex]

or

[tex](-16)^{1/4}=2e^{i 5\pi/8}[/tex]

or

[tex](-16)^{1/4}=2e^{i 9\pi/8}[/tex]

is this correct?
