A) $5 - \sqrt { 10 } i$
B) $- 5 - \sqrt { - 10 } i$
C) $5 - \sqrt { - 10 } i$
D) $- 5 + \sqrt { 10 } i$
E) $5 + \sqrt { 10 } i$

Question

Quizplus · Accepted Answer

The complex conjugate of a complex number of the form $a + bi$ is just $a - bi$. Therefore, the complex conjugate of $-5 - \sqrt{10}i$ is $-5 + \sqrt{10}i$. So, the answer is $\boxed{	extbf{(D)}}$.
