sqrt(-4/16)=color(magenta)(i/2)416=i2

Explanation:

sqrt(-4/16)416
color(white)("XXX")=sqrt(-1) * sqrt(4/16)XXX=1416

color(white)("XXX")=sqrt(-1) * sqrt(1/4)XXX=114

color(white)("XXX")= sqrt(-1) * sqrt(1)/sqrt(4)XXX=114

color(white)("XXX")= i * 1/2 or 1/2 i or i/2XXX=i12or12iori2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I replaced your jj with an ii since from what I have observed here, ii is the more common symbol used here for sqrt(-1)1 (although I have seen jj used elsewhere).

I think the 11 in your suggested answer j/12j12 was just a typo.
