Ответ:
Каждую шестнадцатеричную цифру заменяем тетрадой:
\(3C_{16}=0011\ 1100_2\), \(42_{16}=0100\ 0010_2\), \(91_{16}=1001\ 0001_2\), \(9D_{16}=1001\ 1101_2\), \(81_{16}=1000\ 0001_2\).
Получаем рисунок:
| 0 | 0 | 1 | 1 | 1 | 1 | 0 | 0 |
| 0 | 1 | 0 | 0 | 0 | 0 | 1 | 0 |
| 1 | 0 | 0 | 1 | 0 | 0 | 0 | 1 |
| 1 | 0 | 0 | 1 | 0 | 0 | 0 | 1 |
| 1 | 0 | 0 | 1 | 1 | 1 | 0 | 1 |
| 1 | 0 | 0 | 0 | 0 | 0 | 0 | 1 |
| 0 | 1 | 0 | 0 | 0 | 0 | 1 | 0 |
| 0 | 0 | 1 | 1 | 1 | 1 | 0 | 0 |
