Answer :
3 + 5i
(3 - 5i)(3 + 5i) =
9 + 15i - 15i - 25i^2 =
9 - 25 * -1 =
9 + 25 =
34
or
x = 3 + 5i
x - 3 - 5i = 0
x = 3 - 5i
x - 3 + 5i = 0
(x - 3 - 5i)(x - 3 + 5i) = 0
x^2 - 3x + 5xi - 3x + 9 - 15i - 5xi + 15i - 25i^2 = 0
x^2 - 6x + 34 = 0
Answer= 3+5i
(3 - 5i)(3 + 5i) =
9 + 15i - 15i - 25i^2 =
9 - 25 * -1 =
9 + 25 =

or
x = 3 + 5i
x - 3 - 5i = 0
x = 3 - 5i
x - 3 + 5i = 0
(x - 3 - 5i)(x - 3 + 5i) = 0
x^2 - 3x + 5xi - 3x + 9 - 15i - 5xi + 15i - 25i^2 = 0
x^2 - 6x + 34 = 0
Answer= 3+5i
Answer: Our required conjugate of a complex number is 3+5i.
Step-by-step explanation:
Since we have given that
There is a complex number which has 3 as the real number and -5i as the imaginary part.
So, our required complex number is 3-5i.
We need to find the conjugate of a complex number will be
3+5i as in case of conjugation we only change the sign of imaginary number .
So, our required conjugate of a complex number is 3+5i.
