Hi guys! I lost my MathSolver account (I am MathSolver) because I forgot my password -_-. Anyway... This is my new account! Also, I have a question:
Find all complex numbers $z$ such that $z^4 = -4.$
Note: All solutions should be expressed in the form $a+bi$, where $a$ and $b$ are real numbers.
Please explain thoroughly! Goodnight!!
Also... @CPhil.. This post was flagged for moderation just like what happened to my old lost account... please unflag!
Thanks in advance,
MathSolver's 2nd Account
Maybe it was flagged because of the @ sign.
Oh yeah! Big brain! Also, I notice you're close to surpassing CPhil's high score of $112,000+$!
Since I can't edit, I think I lost my other account due to forgetfulness and not saving the password because I recently got a new computer. Thanks Melody! P.S.
Sorry I didn't post this with the other reply to your answer, I forgot to mention this. I hopefully won't do this in the future! MSFL signing off for tonight! Baiiiiiiiiiiiiiiiiiiiii $\cdot 237648261231313131335675767567657867868767688797897!$.
