我諗樓上第一個計錯左

2進制轉16進制,由於2^4 = 16,
所以我地可以將2進制o個個數由右開始,4個4個一組分好佢:
1011 – 0011 – 0110 – 1111
再將每一組轉做一個十六進制ge符號:
1011(2) = 11(10) = B(16)
0011(2) = 3(10) = 3(16)
0110(2) = 6(10) = 6(16)
1111(2) = 15(10) = 3(16)

所以o個個答案應該係 B363(16)

我知第一個回答者錯咩lu...應該由右手邊第一個位開始係乘2^0,唔係1次方,所以錯左

教你個廢招
由右數向左
1111=2*0+2*1+2*2+2*3=1+2+4+8=15=

1011001101101111(2)=1x2^16+1x2^14+1x2^13+1x2^10+1x2^9+1x2^7+1x2^6+1x2^4+1x2^3+1x2^2+1x2^1
=91869
91869/16=5741...13
5741/16=358....13
358/16=22...6
22/16=1...6
1/16=0...1
1011001101101111(2)=166DD(16)
