which equation demonstrates the additive identity property?\n(7 + 4i)+(7 - 4i)=14\n(7 + 4i)+0 = 7 + 4i\n(7 + 4i)(1)=7 + 4i\n(7 + 4i)+(-7 - 4i)=0
Answer
Explanation:
Step1: Recall additive identity property
The additive - identity property states that for any number (a), (a + 0=a) and (0 + a=a).
Step2: Analyze each option
- Option 1: ((7 + 4i)+(7 - 4i)=14) is an example of adding complex - conjugates.
- Option 2: ((7 + 4i)+0 = 7+4i) follows the additive identity property where (a = 7 + 4i) and the additive identity (0) is added to it.
- Option 3: ((7 + 4i)(1)=7 + 4i) is an example of the multiplicative identity property ((a\times1=a)).
- Option 4: ((7 + 4i)+(-7 - 4i)=0) is an example of additive inverses ((a+(-a)=0)).
Answer:
((7 + 4i)+0 = 7+4i)
