(8+7i)/(3-4i).The first thing you do is to multiply both the numerator and denominator with the conjugate of the denominator.the conjugate is gotten by changing the sign.therefore the conjugate is 3+4i.then you hav (8+7i)x(3+4i) all over (3-4i)x(3+4i).note that i squared is equal to (-1).after the simplification you have (-4+53i)/25.
