What are the steps to understanding this problem as well as the answers.
svetlana [45]

Step-by-step explanation:

1

\frac{1}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{3 - 4i}{25}  =  \frac{ 3}{25} -  \frac{4i}{25}

2)

\frac{1}{3  -  4i}  \times  \frac{3  + 4i}{3  + 4i}  =  \frac{3  + 4i}{25}  =  \frac{ 3}{25}  + \frac{4i}{25}

3)

1+0i

4)

\frac{3 - 4i}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{ - 7 - 24i}{25}  =  -  \frac{7}{25}  -  \frac{24i}{25}

5)

3 - 4i

6)

\frac{3 + 4i}{3 - 4i}  \times  \frac{3 + 4i}{3 + 4i}  =  \frac{ - 7 + 24i}{25}  =  -  \frac{7}{25}  +  \frac{24i}{25}
