Question

Answer 1

a) 1001110₂ -> 1.2⁶+0.2⁵+0.2⁴+1.2³+1.2²+1.2¹+0.2⁰ = 78₁₀

b) 79₁₀ -> 1001111₂

Cách tính:

79:2=39 (dư 1)

39:2= 19 (dư 1)

19:2=9 (dư 1)

9:2=4 (dư 1)

4:2=2 (dư 0)

2:2=1 (dư 0)

1:2=0 (dư 1)

->1001111

c) 1F3AB₁₆ -> 1.16⁴+15.16³+3.16²+10.16¹+11.16⁰ = 127915₁₀

d) 13783₁₀ -> 55D7₁₆

Cách tính:

13783:16=861 (dư 7) -> 7

861:16=53 (dư 13) -> D

53:16=3 (dư 5) -> 5

5:16= 0 (dư 5) -> 5
