It is wrong proof because value of √1 is only 1 but in algebra if there is x^2=1 than x have 2 solutions "1" and " -1"
This is the the basic things that every student should know about this..Some student can get confused in this

This statement is wrong because the plus or minus that we put for the root is not after the completion of the root but outside the root symbol before the root process for example : +- rt(1) = +-1 but rt(1) is always mathematically 1 and can never be +-1.

it cant be 1=-1 bcaz the value of root 1 is 1 or -1 the value can only one not both the main word here is OR👍

I See A Problem...
1.) sqrt(1) = 1 - i (No...)
2.) sqrt(1) = -1 - i^2
= -1 - (-1)
= -1 + 1
= 0 (Also No...)
Therefore, 1 ≠ -1.
(Assuming i = sqrt(-1))
And, Assuming Step 1 Is True, Are You Trying To Say That 1 - i = 0?

i power 4 is 1
-1 power 4 is 1
i=-1
Just kidding
