Homework Statement
Solve for z^4 +16=0
Homework Equations
The Attempt at a Solution
What I first did was square rooted both sides to get z^2 = ±4i, but I don't how to continue from there. I'm guessing we have to find the roots from z^2=4i and then from z^2=-4i separately any help will be much appreciated!
