$$\frac{ 10 }{ 8-5i}$$
You can seperate it into this
$$\frac{ 10 }{ 8 }-\frac{ 10 }{ 5i }$$
Then you simplify 10/8 
And for 10/5i, it is the same as $$\frac{ 10 }{ \sqrt{-5} }$$
You can multiply that by the irrational denominator so
$$\frac{ 10 }{ \sqrt{-5} } \times \frac{ \sqrt{-5} }{ \sqrt{-5} }$$
It will become
$$\frac{ 10*\sqrt{-5} }{ -5 }$$
I can only get to that far because I am not sure how to simplify the top. I think you can still simplify it, but I am not sure.

No problem, you might want to double check just in case
