Which of the following is the conjugate of a complex number with 2 as the real part and -8 as the imaginary part?

-2 + 8i

2 + 8i

2 - 8i

-2 - 8i

Answer 1

You can break the question apart and notice that they are asking for
Real Part:
2
Imaginary part:
-8

Recall that imaginary numbers are represented as (number)i so knowing that you can now figure out the correct answer

Answer 2

2-8i? @Johnbc

Answer 3

Almost there, now do not forget the most important part they asked for the CONJUGATE of that complex number

Answer 4

Conjugate means that you change the sign in the middle

Answer 5

so it would be 2+8i correct?

Answer 6

Correct! Great Job!

Answer 7

Thank you so much!

Answer 8
