    Answer:

    Step-by-step explanation:

    We are given z = 9 + 3i

    It is complex number which has one real and one imaginary part.

    z = a + bi

    a is real

    b is imaginary (coefficient of i)

    For given number

    9 is real

    3 is imaginary

    For conjugate , flip the sign of i

    a + bi  conjugate is a – bi

    Therefore, The conjugate of 9 + 3i is  9 – 3i

      # Match the following :-

    1. Real part of z                                -9

    2. Imaginary part of z                  3

    3. Complex conjugate of z          9-3i

    4. 3i – z                                         9

    5. z-9                                                -3i

    6. 9-z                                                 3i

    Real part of z = 9
    Imaginary Part = 3i
    Conjugate of z is 9 – 3i
