They can't. No one can. You won math.

>>7800413
all you did was manipulate the fact that
sqrt(1) = +-1

>>7800425

do you even math?

>>7800413

sqrt(x)^2 = |x|

>>7800457

This only applies in highschool math

How does (sqrt(-1))^2 = sqrt((-1)^2)?

(sqrt(-1))^2 = -1

sqrt((-1)^2) = 1

>(sqrt -1)^2 = sqrt (-1)^2

Lol no

>>7800427
OP proved that sqrt(1) = +-1. It's not really that difficult of a concept to grasp

>rooting the square is equal to squaring the root

are people actually this retarded? maybe you should take your meds before posting OP.

>>7800498

kekked hard, are you fucking dumb?

(sqrt(2))^2 = sqrt(2^2)

try your calculator since you probably won't be able without, fuckwit

>>7800496

>He actually believes this.

sqrt(1)=1 =/= -1

That's why any serious mathmatician defines i^2 = -1

>>7800506
Now try it with -2

>>7800515

You don't get it, do you?

>>7800510

This board calls itself /sci/ and there's only one person who can math

top kek

>>7800515

if you can't root negative numbers, then why can you root -1?

that's what the thread is about dipshit, its evident that you can't root -2

>>7800520
If by it you mean a real result, I don't because (sqrt(-2))^2 =/= sqrt(-2^2) ya dingus

>>7800531
No, the thread is about how ops image says square of root = root of square which is incorrect for negative numbers

And imaginary numbers bro

Oh look, it's the thread where no one knows about branch points again.
