Answer 1

Răspuns:

a) 101₍₂₎ = 5₍₁₀₎

b) 1101₍₂₎ = 13₍₁₀₎

c) 10110₍₂₎ = 22₍₁₀₎

d) 11001₍₂₎ =  25₍₁₀₎

Explicație pas cu pas:

a) 101₍₂₎ = 1·2²+0·2¹+1·2⁰ = 4+0+1 = 5₍₁₀₎

b) 1101₍₂₎ = 1·2³+1·2²+0·2¹+1·2⁰ = 8+4+0+1 = 13₍₁₀₎

c) 10110₍₂₎ = 1·2⁴+0·2³+1·2²+1·2¹+0·2⁰ = 16+0+4+2+0 = 22₍₁₀₎

d) 11001₍₂₎ = 1·2⁴+1·2³+0·2²+0·2¹+1·2⁰ = 16+8+0+0+1 = 25₍₁₀₎
