is it $$\frac{8i}{-1}+3i$$ or $$\frac{8i}{-1+3i}$$

$$\frac{8i}{-1+3i}=\frac{8i}{-1+3i}\frac{-1-3i}{-1-3i}$$ $$=\frac{8i(-1-3i)}{(-1+3i)(-1-3i)}$$ $$=\frac{-8i+24}{(1+9)}$$ $$=\frac{-8i+24}{10}=\frac{-4i+12}{5}=\frac{12-4i}{5}$$

what
ok 8i(-1-3i)/(-1-3i)((-1-3i) can't be 8i+24/ 1+9 because 8i(-1-3i)= -8i-24i^2
\[8i(-1-3i)=-8i-24i^2=-8i-24(-1)=-8i+24\]
ah ok
thankss alot
