    to answer this question, you need to know what the complex conjugate.

    so when dividing complex numbers, you have to multiply the numerator and denominator by the complex conjugate of the equation in the denominator.

    (5-2i/3-4i)*(3+4i/3+4i) + (1+6i/7-i)*(7+i/7+i)

    now you multiply out. you should get

    (23+14i/25)+(1+43i/48)

    you can put them into one equation if you want.

    hope this helps!
