Answer 1

10 101(2) = 1 × 2^4 +1 × 2^2 + 1 × 2^0 =

= 16 + 4 + 1 =

= 21
_____

110(2) = 1 × 2^2 + 1 × 2^1 = 4 + 2 = 6
_______

11 010(2) = 1 × 2^4 + 1 × 2^3 + 1 × 2^1 =

= 16 + 8 + 2 =

= 26
_____

100 000(2) = 1 × 2^5 = 32

Answer 2

a)

10 101 = 1·2⁴ + 0·2³ + 1·2² + 0·2¹ + 1·2⁰ = 16 + 0 + 4 + 1 = 21

b)

110 = 1·2² + 1·2¹ + 0·2⁰ = 4 + 2 + 0 = 6

c)

11 010 = 1·2⁴ + 1·2³ + 0·2² + 1·2¹ + 0·2⁰ = 16 + 8 + 0 + 2 + 0 = 26

d)

100 000 = 1·2⁵ + 0·2⁴ + 0·2³ + 0·2² + 0·2¹ + 0·2⁰ = 32 + 0 + 0 + 0 + 0 + 0 = 32
