URGENT: Complex Numbers Problems: HELP NEEDED FOR MY FINAL EXAM!!? Q1: Write the numbers in the form a+b: i) (2+3i)/(1+2i) - (8+i)/(6-i) ii) [(2+i)/(6i-(1-2i))]^2 Q2: Simplify: i) i^11 ii) i^203 Q3: Show that the points: 1, -1/2 + (i*squareroot(3))/2, -1/2 - (i*squareroot(3))/2 are the vertexes of an equilateral triangle. Q4: Describe: i) | 2Z - i |= 4 ii) | Z | = 3 |Z - 1| Q5: Write in Polar Form: i) (1+i)/[squareroot(3)-1] ii) -2*squareroot(3) - 2i iii) (1-i) (-squareroot(3)*i) iv) (-1 + squareroot(3)*i)/(2+2i) Can you please show detailed solution for each one because I don't get the lesson.. I don't have that part in my book, and it is included in my final exam after 3 days. I hope you can help me..Thanks alot in advance!
