Question

What is the complex conjugate of 13-21i?

Answer 1

The conjugate of "anything" is pretty much the same binomial, with a different sign.

ducks + geese     conjugate ->  ducks - geese

cheese - spaghetti     conjugate -> cheese + spaghetti

and so on and so forth.

well, for this one, yeap, you guessed it

 13 - 21i     conjugate -> 13 + 21i.

Answer 2

Answer:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i). This means that it either goes from positive to negative or from negative to positive.

As a general rule, the complex conjugate of a+bi is a−bi.

Therefore, the complex conjugate of 3−2i is 3+2i.

Hope this helped!!... :D

Please correct me if I'm wrong!!.. :3
