the additive inverse of non complex 9 is -9 .
<u>Step-by-step explanation:</u>
Complex number is said to be the sum of whole numbers and imaginary numbers.The additive inverse of the any number is the changing the sign of the number. That is instead –ve sign is positive and vice versa.
Additive Inverse of Complex Numbers:
Let take the complex numbers and its inverse be
Step 1: Now add the Z and Z-1, we get
Step 2: Combine Like term, we get
Step 3: By using zero product property, we can equating as
and
and
Thus, the additive inverse of the complex numbers .
Now, additive inverse of =
.
Therefore , the additive inverse of non complex 9 is -9 .
