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

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 $\cdot 237648261231313131335675767567657867868767688797897!$.
