Answer 1

a) 11(2) = 1×2¹ + 1×2⁰ = 2+1 = 3

b) 1011(2) = 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 8+2+1 = 11

c) 1100(2) = 1×2³ + 1×2² + 0×2¹ + 0×2⁰ = 8+4 = 12

d) 10111(2) = 1×2⁴ + 0×2³ + 1×2² + 1×2¹ + 1×2⁰ = 16+4+2+1 = 23

e) 1101101(2) = 1×2⁶ + 1×2⁵ + 0×2⁴ + 1×2³ + 1×2² + 0×2¹ + 1×2⁰ = 64+32+8+4+1 = 109

f) 10011(2) = 1×2⁴ + 0×2³ + 0×2² + 1×2¹ + 1×2⁰ = 16+2+1 = 19
