Question

What is the additive identity of the complex number 14 + 5i?

A) 14 – 5i
B) 0
C) 1
D) –14 – 5i

Answer 1

The answer is B. 0

Answer 2

Answer: B) 0

Explanation:

1. When you add complex numbers you must add the whole parts and then the imaginary parts.

2. One of the properties of complex numbers is called "Additive identity" which is represented by:

`0+0i`

3. Then, for the complex number
`14+5i`, you have:

`(14+5i)+(0+0i)=(14+0)+(5+0)i=14+5i`

4. Therefore, the answer is the option B.
