✔ 最佳答案
1.(a)
2^6 + 1
= 1´2^6 + 0´2^5 + 0´2^4 + 0´2^3 + 0´2^2 + 0´2 + 1
= 1000001(2)
(b)
1´16^3 + 10´16^2 + 13x16 + 3
= 1AD3(16)
2.
(a)
The place value of the digit '5' = 1000
The place value of the digit '6' = 100
The place value of the digit '4' = 10
The place value of the digit '8' = 1
(b)
5648
= 5´1000 + 6´100 + 4´10 + 8
= 5´10^3 + 6´10^2 + 4´10 + 8
3.
B(16) = 11(10) = 1011(2)
A(16) = 10(10) = 1010(2)
0(16) = 0(10) = 0000(2)
3(16) = 3(16) = 0011(2)
BA03(16) = 1011101000000011(2)
