Please help with these simple questions just not understanding it properly.
Find square root, of -6i
let sqroot of -6i= x+ yi
then -6i=x^2 - y^2 +2xyi
x^2 - y^2 = 0 and 2xy=-6
then xy=-3
x=-3/y
and then solve simu..
i got y= 3 and x=-1 y=-3 x=1
so the anser is +_(-1+3i)
BUt that isn't the answer, please help
one more
square root of
i,
sqroot of i= x+yi
i=x^2-y^2+2xyi
then x^2-y^2= 0 and 2xy=sqroot -1
I am a bit lost around here. Please help.
