Answer 1

Answer:

1-(i)(10010)₂ = (1 × 2⁴) + (0 × 2³) + (0 × 2²) + (1 × 2¹) + (0 × 2⁰) = (18)₁₀

(ii) (10101)₂ = (1 × 2⁴) + (0 × 2³) + (1 × 2²) + (0 × 2¹) + (1 × 2⁰) = (21)₁₀

(iii) (1011)₂ = (1 × 2³) + (0 × 2²) + (1 × 2¹) + (1 × 2⁰) = (11)₁₀

2-(i) 10101 + 00111

= 011100

(ii) 1000101101 + 1001101

= 01001111010

(iii) 1101 + 1001

= 010110
