QuestionSimplify each expression:
1. $(2+7 i)+(5+i)$
2. $(4+2 i)-(1+i)$
3. $(11+5 i)-(2-2 i)$
4. $(8-3 i)-(3)$
5. $(6-2 i)+(4+6 i)$
6. $(5 i)-(1+i)$
7. $(1+3 i)-(1-i)$
8. $(9-4 i)+(4 i)$

Studdy Solution
1. $(2+7i)+(5+i)$ simplifies to $7 + 8i$.
2. $(4+2i)-(1+i)$ simplifies to $3 + i$.
3. $(11+5i)-(2-2i)$ simplifies to $9 + 7i$.
4. $(8-3i)-(3)$ simplifies to $5 - 3i$.
5. $(6-2i)+(4+6i)$ simplifies to $10 + 4i$.
6. $(5i)-(1+i)$ simplifies to $-1 + 4i$.
7. $(1+3i)-(1-i)$ simplifies to $4i$.
8. $(9-4i)+(4i)$ simplifies to $9$.
