Best ResponseYou've already chosen the best response.0Basically, you have to rationalize the denominator which means to get rid of 'i' in the denominator. THat means that you have to multiply by the conjugate in the denominator. \[\frac{7 + 2i}{4  3i} \implies \frac{7 + 2i}{4  3i} \times \frac{4 + 3i}{4 + 3i} \implies~?\]
