1. Skryf die volgende in terme van i :

1.1 \( \sqrt{-25} \) 1.2 \( \sqrt{-9 } \) 1.3 \( \sqrt{-2} \)

2. Vereenvoudig:

2.1 \(i^{102} \) 2.2 \( i^{63} \)

2.3 \( (2+6i) - (4-2i) - (5+4i) \) 2.4 \( i^{61} .(5-2i) \)

2.5 \( (2+4i)(5-2i) \) 2.6 \( (2+5i)(2-5i) \)

2.7 \( 1+3i+ (3-2i) \) 2.8 \( 5+2i+ (7+6i) \)

2.9 \( 5-7i-(2+3i) \) 2.10 \( 6+3i-(6-5i) \)

2.11 \( 3-2i(4+2i) \) 2.12 \( 6-i(2+3i) \)

2.13 \(4+i(2-3i) \) 2.14 \( 2+3i(1+4i) \)

2.15 \( (2+i)^2 \) 2.16 \( (5-2i)^2 \)

2.17 \( 2i^3 (1-4i)^2 .(5-i)(5+i) \)

3. As a+bi=z , bepaal die waardes van a en b in die volgende:

3.1 \( z=-2+i \) 3.2 \( z=(7-9i)( \frac{i}{2} -1) \)
