I saw this thing where someone proved that the imaginary number, i, the sqrt(-1) was equal to 1.(adsbygoogle = window.adsbygoogle || []).push({});

here it is:

i= sqrt(-1)

i^2 = [sqrt(-1)]^2

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

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

i^2 = sqrt(1)

i^2 = 1

so

i = 1

I know theres something wrong here but i can't figure it out. any help???
