(5+i)/(3-2i)
===============
That's not a problem, just an expression.
You didn't say what you want to do.
-----
Usually, it's "rationalize" the denominator, ie, make it a real number. The possible answers indicate that, too, but it's your job to state what you want to do.
------
(5+i)/(3-2i)
Multiply the NUM & DEN by the conjugate of the DEN, 3+2i
= (5+i)*(3+2i)/((3-2i)*(3+2i)
= (15 + 13i - 2)/(9+4)
= (13 + 13i)/13
= 1 + i
