Ok, so which of the following statements are false according to you?

i^4 = -1

 C'est vrai.
 

i^2 = -1

 C'est vrai.
 

i^2 = i * i

 C'est vrai.
 

i^4 = i * i * i * i

 C'est vrai.
 

i^4 = i^2 * i^2

 C'est vrai.

 So basically you're saying
 -1 * -1 = -1

 No.

Because that is the way the equality relation works in math.

 No.  Not in complex mathematics.
 If you want to use complex numbers, you have to use the laws of complex numbers.
So you have to use i^x=-1 whatever x is.
Otherwise, it's like eating soup with a fork.
