explain this, faggots

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.
