Perform the indicated operation. Write the result in the form a + bi.
-$( 2 - 2 i ) + ( 8 + 8 i )$
A) $- 6 + 10 \mathrm { i }$
B) $10 - 6 i$
C) $10 + 6 i$
D) $- 10 - 6 i$

Quizplus · Accepted Answer

To add the complex numbers $(2 - 2i) + (8 + 8i)$, add the real parts together and the imaginary parts together: $2 + 8 = 10$ and $-2i + 8i = 6i$. Thus, the result is $10 + 6i$.

Perform the Indicated Operation (2−2i)+(8+8i)( 2 - 2 i ) + ( 8 + 8 i )(2−2i)+(8+8i)

Perform the Indicated Operation $( 2 - 2 i ) + ( 8 + 8 i )$
