Sorry, I know this is a repost, but it won't let me edit. https://web2.0calc.com/questions/pre-calc-help-please If I say z^n=1, could I do (1e2πik7−1)7=z7, then 1(e2πik7−1)7? Idk tbh. Any help is greatly appreciated!! thank you in advanced
Sorry, I'm not sure if my question is clear then. I already found the solutions: z=1e2πi7−1,1e4πi7−1,1e6πi7−1,1e8πi7−1,1e10πi7−1,1e12πi7−1 I am struggling to find how to prove all of those solutions have the same real part and what that real part is. This equation is a 7th root of unity so there has to be some "trick"
