Question

Find real numbers a and b such that the equation is true.​ $a + b i = - 8 + 18 i$ ​
A) $a = - 12 , b = 22$
B) $$a = - 10 , b = 20$$
C)​ $a = - 11 , b = 21$
D) $a = - 9 , b = 19$
E) $$a = - 8 , b = 18$$

Quizplus · Accepted Answer

The equation $a + bi = -8 + 18i$ directly matches the form of a complex number, where $a$ is the real part and $b$ is the imaginary part. Therefore, $a = -8$ and $b = 18$, which corresponds to choice E.
