Operations with Complex Numbers
Simplify.
1. sqrt(144)
2. sqrt(64x^4)
3. sqrt(13)*sqrt(26)
4. (2i)(6i)(4i)
5. i13
6. i38
7. (5 – 2i) + (4 + 4i)
8. (3 – 4i) – (1 – 4i)
9. (3 + 4i)(3 – 4i)
10. (6 – 2i)(1 + i)
11. (4i)/(3+i)
12. (10+i)/(4i)
13. (5 + 2i)(6 – i)(4 + 3i)
14. (5i*sqrt(3))/(5+i*sqrt(3))
15. Find the sum of
ix2 – (2 + 3i)x + 2 and 4x2 + (5 + 2i)x – 4i.
Solve each equation.
16. 5x2 + 5 = 0
17. 2x2 + 12 = 0
18. 3x2 – 9 = 0
19. (2/3)x2 + 30 = 0
Find the values of m and n that make each equation true.
20. 8 + 15i = 2m + 3ni
21. (2m + 5) + (1 – n)i = 2 + 4i
22. (m + 2n) + (2m – n)i = 5 + 5i

accidently posted the wrong thing, i will re post the right assignment for help thankyou!!!
