5 + 2i
−5 − 2i
−5 + 2i
5 − 2i
Answer: the correct option is
(A) 5 + 2i.
Step-by-step explanation: We are given to select the complex number that is the conjugate of a complex number with 5 as the real part and −2i as the imaginary part.
We know that
a complex number z can be written as
z = a + bi, where a is the real part and bi is the imaginary part.
According to the given information, we have
a = 5 and b = -2i
So, z = 5 - 2i.
Therefore, the conjugate of z is given by
Thus, the required conjugate number is 5 + 2i.
Option (A) is CORRECT.
