Maths:進制

1. Use binary numbers to represent 1×2(6) + 1×2(4) + 1×2(3)
= 1011000 [二進數]

2. Use hexadecimal number to represent 12×16(3) + 9×16+14
= C09E [十六進數]
[because C = 12，E = 14]

3.Write the numbers below in the expanded form.
(a) 2601
= 2x103 + 6x102 + 1

(b) 10111.....2
= 1x24 + 1x22 + 1x2 + 1

(c) E8A...16
= 14x162 + 6x16 + 10
[because E = 14，A = 10]
