Answer 1

Ответ:

1.

86₁₀ = 0*2⁰ + 1*2¹ + 1*2² + 0*2³ + 1*2⁴ + 0*2⁵ + 1*2⁶ = 1010110₂

86₁₀ = 6*8⁰ + 2*8¹ + 1*8² = 126₈

86₁₀ = 6*16⁰ + 5*16¹ = 56₁₆

111010₂ = 0*2⁰ + 1*2¹ + 0*2² + 1*2³ + 1*2⁴ + 1*2⁵ = 58₁₀

58₁₀ = 2*8⁰ + 7*8¹ = 72₈

58₁₀ = 10*16⁰ + 3*16¹ = 3A₁₆

46₈ = 6*8⁰ + 4*8¹ = 38₁₀

38₁₀ = 0*2⁰ + 1*2¹ + 1*2² + 0*2³ + 0*2⁴ + 1*2⁵ = 100110₂

38₁₀ = 6*16⁰ + 2*16¹ = 26₁₆

2F₁₆ = F*16⁰ + 2*16¹ = 47₁₀

47₁₀ = 1*2⁰ + 1*2¹ + 1*2² + 1*2³ + 0*2⁴ + 1*2⁵ = 101111₂

47₁₀ = 7*8⁰ + 5*8¹ = 57₈

55₁₀ = 1*2⁰ + 1*2¹ + 1*2² + 0*2³ + 1*2⁴ + 1*2⁵ = 110111₂

55₁₀ = 7*8⁰ + 6*8¹ = 67₈

55₁₀ = 7*16⁰ + 3*16¹ = 37₁₆

2.

76₈ < 93₁₀ < 1101111₂ < A9₁₆

1101111₂ = 1*2⁰ + 1*2¹ + 1*2² + 1*2³ + 0*2⁴ + 1*2⁵ + 1*2⁶ = 111₁₀

A9₁₆ = 9*16⁰ + A*16¹ = 169₁₀

76₈ = 6*8⁰ + 7*8¹ = 62₁₀

93₁₀ =  = 93₁₀

3.

110111₂ = 1*2⁰ + 1*2¹ + 1*2² + 0*2³ + 1*2⁴ + 1*2⁵ = 55₁₀

135₈ = 5*8⁰ + 3*8¹ + 1*8² = 93₁₀

55₁₀  + 93₁₀  = 148₁₀

148₁₀ = 0*2⁰ + 0*2¹ + 1*2² + 0*2³ + 1*2⁴ + 0*2⁵ + 0*2⁶ + 1*2⁷ = 10010100₂

ответ 4. 10010100₂
