To form the additive inverse, negate all parts of the complex number
→ 8 + 3i → -8 - 3i
The sum of a number and its additive inverse is 0:
(8 + 3i) + (-8 - 3i) = (8 + -8) + (3 + -3)i = (8 - 8) + (3 - 3)i = 0 + 0i = 0.

∙ 8y agoJust change every plus to minus, and every minus to plus. In this case, if you mean 8 + 3i, change it to -8 - 3i.As a check, the original number, plus its additive inverse, must have a sum of zero.

What is the inverse of -x5 - 2x plus 2?
The additive inverse is x5 + 2x - 2.
Additive inverse of -12?
Additive inverse means that you are supposed to change the sign:* If there is a plus sign (or no sign at all), change it to a minus. * If there is a minus sign (as in this case), change it to a plus (or no sign).
What is the additive of -4?
If you mean the ADDITIVE INVERSE, change the minus sign to a plus sign. (And if you see a plus sign, you change it to a minus sign.)
Name the property illustrated by the following x plus -x equals 0?
This is the existence of additive inverse: For every number, x, there exists a number, denoted by (-x), such that x + (-x) = (-x) + x = 0.
What is the multiplicative inverse of 4 plus i?
To find the multiplicative inverse of a complex number z = (a + bi), divide its complex conjugate z* = (a - bi) by z* multiplied by z (and simplify): z = 4 + i z* = 4 - i multiplicative inverse of z: z* / (z*z) = (4 - i) / ((4 - i)(4 + i) = (4 - i) / (16 + 1) = (4- i) / 17 = 1/17 (4 - i)
What is additive inverse and a additive identity?
additive inverse is when in an equation there is a plus zero. you automatically know that anything plus 0 is still that number, so that is additive identity.
What is the additive inverse of 6 plus 4i?
The additive inverse of 6+4i is -6-4i since their sum is 0. It is analogous to real numbers where the additive inverse of 6 is -6 since 6+-6 =6-6=0 In the case of complex numbers, we add them by adding the real parts and then adding the imaginary parts. So to find the complex additive inverse of a+bi, we find the inverse of a which is -a and of bi which is -bi and so the additive inverse is -a-bi
What is the property shown in -7 plus 7 equals 0?
Additive inverse of a number a is that number which on addition with a gives 0.7 is additive inverse of -7.The property shown is additive inverse property because the addition yields 0.
Is 7k plus 0 equals 7k a multiplicative identity?
No because 0 is additive inverse the multiplicative inverse of a number is when you multiply that number by the m. inverse and still get that number.
What is the additive inverse of -0.125?
To find the additive inverse of any number, just change the plus sign (or no sign) to a minus sign, or (as in this case), if there already is a minus sign, change it to a plus sign (or no sign).
What is the difference between additive identity and additive inverse?
The additive inverse is a number subtracted it's self is 0: x + (-x) = 0 The additive identity is a number plus/minus 0 is itself: x +/- 0 = x They're very similar
What is the definition of the Additive inverse property?
Any number plus zero is equal to the original amount.
What is the inverse of -7 plus 5?
It depends on whether you mean additive inverse or multiplicative inverse.
What is an additive inverse property?
the additive inverse property states that a number plus it's opposite equals zero. in other words, x + (-x) = 0 example: 5 + (-5) = 0
What is the additive inverse of -4.7?
4.7 (or PLUS 4.7)
What is the inverse of -x5 - 2x plus 2?
The additive inverse is x5 + 2x - 2.
What is the additive inverse of negative3w plus 10?
It is 3w - 10
