198^2 + 396 x 2 + 4
198^2 + 4 x 198 + 4
198(198+4) + 4
198 x 202 + 4
198 (200+2) + 4
198 x 200 + 198 x 2 + 4
39600 + 396 + 4
39600 + 400
40000
atau
198^2+792+4 = 198^2+796
198^2
Mendekati 200
198-(200-198) = 198-2 = 196
Kalikan 2, 196 x 2 = 392
Tambahkan hasil pengurangan tadi (2), lalu kuadratkan,
2^2 = 4 karena satuan kasih 0, jadi 04
Tempelin, 198^2 = 39204
32904+796 = 40000
