hey /sci/

can you help me out with this mathematical paradox, I can't seem to find the fallacy in it.

√ = A radical btw
Here it is

√ -1 = √ -1
√ -1/1 = √ -1/1
√ -1/√ 1=√ -1√ 1
√ -1 x √ -1 = √ 1 x √ 1

Sorry, it's kinda hard to read like that. Any help would be appreciated.

Thanks /sci/

o shi

forgot the last part

-1=1

The product of a radical is an absolute value.

it's a radical

Ah, so you are saying that you can't even multiply √ -1 because it is false and isn't an absolute value?

Negative numbers aren't valid for finding the even roots. Now if you affix a superscripted 3 before the radical...

looks like you forgot a division bar on the 3rd row.

also if you squareroot you need a plus minus.

>> No.1075886

>>1075873
whoops, you are correct, I did forget the division bar.

>> No.1075922

√ -1/√ 1=√ -1/√ 1
Removing the √'s to make it more readable...
-1/1 = -1/1
How did you get those to the next step? As I see it, you should get √-1 / √-1=√1 / √1
