✔ 最佳答案
1. (3D7)16 = ( )10 = (983)10
2. (101101)2 = ( )10 = (45)10
3. (1001101101)2 = ( )8 = ( )16 = (1155)8 = (26D)16
4. (2CI)16 = ( )2 = ( )8 = 1011000001(2) = (1301)8
5. (101101)2 = ( )10 = ( )16 = (45)10 = (2D)16
6. (A4)16 = ( )2 = ( )8 = (10100100)2 = (244)8
7. (27)8 = ( )2 = ( )10 = (10111)2 = (23)10
8. (100110)2 = ( )8 = ( )16 = (46)8 = (26)16
9. (10010110)2 - (1001)2 = ( )2 = (10001101)2
10. (1110)2 x (1001)2 = ( )2 = (1111110)2
11. (1100100)2 、 (56)2 、 (135)8 、 (4A)16 , 由大至小排列

(1100100)2 = (100)10
(56)2 = ?????
(56)10 = (56)10
(135)8 = (93)10
(4A)16 = (74)10

(56)10 < (4A)16 < (135)8 < (1100100)2

其實用 附屬應用程式 小算盤 檢視 工程型 便可以按出來了。

2014-02-03 14:39:57 補充:
12. 數值3 = ( )2 = (00000011)2

13. 文字 " 3 " = ( )2 = (00110011)2
