you need the sqaure root of -49?
@Japs here, this is what my problem looks like
i believe the answer is 7 i, i think i hope it helps and is right. :D
\(\sqrt{-49}=\sqrt{49}\times \sqrt{-1}=7i\)
\((3+4i)-(2-5i)=3+4i-2+5i=1+9i\)

@satellite73 these arent helping?
that is what you need to start the problem
you need to start with \[\frac{7i}{1+9i}\] and then write in standard from by multiplying top and bottom by \(1-9i\)
so the bottom part is 10 with the who equation as a negative?
