- 4. (i) 82 (10 - 2)2
- 5. (i) 82 (10 - 2)2
- 6. (i) 82 (10 - 2)2
- 7. 102 - 10 x 2 - 10 x 2 + 22 = 100 = 20 = 20 = 4 64 100 – 2 x 20 + 4 = 64
- 8. More examples (ii) 292 (30 - 1)2 302 = 900 - 2 x 30 x 1 = -60 840 + 12 = 1 841
- 9. More examples (iii) 472 (50 - 3)2 502 = 2500 - 2 x 50 x 3 = -300 2200 + 32 = 9 2209
- 10. More examples (iv) 1922 (200 - 8)2 2002 - 2 x 200 x 8 + 82 = 40000 = -3200 36800 = 64 36864
- 11. More examples (v) 2472 (250 - 3)2 2502 - 2 x 250 x 3 + 32 = 62500 = -1500 61000 = 9 61009
