Question 1176550
<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{25}{Z_1}\ =\ 3\,-\,4i]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{25}{Z_1}\ =\ 3\,-\,4i\(\frac{3\,+\,4i}{3\,+\,4i}\)\ =\ \frac{25}{3\,+\,4i}]


Hence


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ Z_1\ =\ 3\,+\,4i]


Therefore


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \overline{Z_1}\ =\ 3\,-\,4i]
