Best ResponseYou've already chosen the best response.1Now you have to find this in the form z = x + iy.. So: \[\frac{10 + 100i}{101} \implies \frac{10}{101} + i \frac{100}{101}\]

Best ResponseYou've already chosen the best response.0yes , i do understand . but my teacher already give me an answer for this , he said it should be 10+i and i must find the way to get 10 + i

Best ResponseYou've already chosen the best response.1See your teacher said to you want to solve this by using \(10 + i\) Here we have done the same ..

Best ResponseYou've already chosen the best response.1The conjugate of \(10  i\) is \(10 + i\) So we have multiplied and divide it by the conjugate that is : \(10 + i\)

Best ResponseYou've already chosen the best response.0i dont understand . we've got 10/101+i100/101 and my teacher said 10+i as the answer

Best ResponseYou've already chosen the best response.1I think he just said to find conjugate so then the answer should be \(10 + i\)

Best ResponseYou've already chosen the best response.1\[\frac{11 + 2i}{4 + 3i} \times \frac{4  3i}{4  3i} \implies \frac{44  33i + 8i  6i^2}{(4)^2  (3i)^2} \implies \frac{44  25i 6(1)}{169i^2}\] \[\frac{44  25i + 6}{16  9(1)} \implies \frac{50  25i}{16 + 9} \implies \frac{50  25i}{25} \implies \frac{50}{25}  i \frac{25}{25} \implies 2  i\]
