AB = 1010101199 = 10011001
1 or 1 = 1
1 or 0 = 1
0 or 1 = 1
0 or 0 = 0
AB or 99 = 10111011

3.
答案是： (D) BB。
AB16
= 10x16 + 11
= (8 + 2) x 16 + (8 + 2 + 1)
= (1x2³ + 0x2² + 1x2 + 0) x 16 + (1x2³ + 0x2² + 1x2 + 1)
= 101010112
9916
= 9x16 + 9
= (8 + 1)x16 + (8 + 1)
= (1x2³ + 0x2² + 0x2 + 1)x16 + (1x2³ + 0x2² + 0x2 + 1)
= 100110012
OR 的運算：
0 OR 0 = 0
0 OR 1 = 1
1 OR 0 = 1
1 OR 1 = 1
101010112
100110012
運算的結果
= 10111011
= (1x2³ + 0x2² + 1x2 + 1)x16 + (1x2³ + 0x2² + 1x2 + 1)
= 11x16 + 11
= BB16
答案是： (D) BB。
AB16
= 10x16 + 11
= (8 + 2) x 16 + (8 + 2 + 1)
= (1x2³ + 0x2² + 1x2 + 0) x 16 + (1x2³ + 0x2² + 1x2 + 1)
= 101010112
9916
= 9x16 + 9
= (8 + 1)x16 + (8 + 1)
= (1x2³ + 0x2² + 0x2 + 1)x16 + (1x2³ + 0x2² + 0x2 + 1)
= 100110012
OR 的運算：
0 OR 0 = 0
0 OR 1 = 1
1 OR 0 = 1
1 OR 1 = 1
101010112
100110012
運算的結果
= 10111011
= (1x2³ + 0x2² + 1x2 + 1)x16 + (1x2³ + 0x2² + 1x2 + 1)
= 11x16 + 11
= BB16
