Answer 1

a)

1111₍₂₎ =

= (1·2⁰+1·2¹+1·2²+1·2³)₍₁₀₎

= (1+2+4+8)₍₁₀₎

= 15₍₁₀₎

b)

10001₍₂₎ =

= (1·2⁰+0·2¹+0·2²+0·2³+1·2⁴)₍₁₀₎

= (1+0+0+0+16)₍₁₀₎

= 17₍₁₀₎

c)

101011₍₂₎

= (1·2⁰+1·2¹+0·2²+1·2³+0·2⁴+1·2⁵)₍₁₀₎

= (1+2+0+8+0+32)₍₁₀₎

= 43₍₁₀₎

d)

11111101₍₂₎ =

= (1·2⁰+0·2¹+1·2²+1·2³+1·2⁴+1·2⁵+1·2⁶+1·2⁷)₍₁₀₎

= (1+0+4+8+16+32+64+128)₍₁₀₎

= 253₍₁₀₎
