  1. Answer:

    Let z=

    5

    +3i

    Then,

    z

    ˉ

    =

    5

    −3i and ∣z∣

    2

    =(

    5

    )

    2

    +3

    2

    =5+9=14

    Therefore, the multiplicative inverse of

    5

    +3i is given by

    z

    −1

    =

    ∣z∣

    2

    z

    ˉ

    =

    14

    5

    −3i

    =

    14

    5

    14

    3i
