Solving x^4=16. Don’t take the 4th root! 

(x-2)(x+2)(x^2+4)

Ayoo same pfp

​@skill_issuesmo7367 x²+4 is just difference of squares in disguise! x²-4i² = x²+4

yes. it is called the Fundamental Algebraic Theorem ( in Complex Numbers).

Yes, but with the exception of 0.

@@atzuras thx

cheating

you only found one root

Probably because some people like this format.

Let the coefficient of x (-4) be 3st Let the constant (64) be s^3 - t^3 Let x^3 be (s-t)^3 Solve s-t for x Visual proof: m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2XbFT1hWT_k.html&pp=ygUcRGVwcmVzc2VkIGN1YmljIHZpc3VhbCBwcm9vZg%3D%3D

The simplest approach.

Idk why ppl do such complex methods when we have THIS

Aint that just rooting it?

Sometimes science is about "Why not?"

Because all complex numbers (other than 0) have precisely 4 4th roots. Gotta catch 'em all.
