помогите пожалуйста ​

Ответ:

А) 1101011₂ - 11111₂ = 1001100₂

Б) 100001₂  + 11100₂ = 111101₂

В) 33₈ + 117₈ = 152₈

Г) 72₈ - 46₈ =  = 24₈

Д) 2F₁₆ +  D1₁₆ = 100₁₆

Е) FD₁₆ - AF₁₆ = 4E₁₆  

Объяснение:

1101011₂ = 1*2⁰ + 1*2¹ + 0*2² + 1*2³ + 0*2⁴ + 1*2⁵ + 1*2⁶ = 107₁₀

11111₂ = 1*2⁰ + 1*2¹ + 1*2² + 1*2³ + 1*2⁴ = 31₁₀

76₁₀ = 0*2⁰ + 0*2¹ + 1*2² + 1*2³ + 0*2⁴ + 0*2⁵ + 1*2⁶ = 1001100₂

100001₂ = 1*2⁰ + 0*2¹ + 0*2² + 0*2³ + 0*2⁴ + 1*2⁵ = 33₁₀

11100₂ = 0*2⁰ + 0*2¹ + 1*2² + 1*2³ + 1*2⁴ = 28₁₀

61₁₀ = 1*2⁰ + 0*2¹ + 1*2² + 1*2³ + 1*2⁴ + 1*2⁵ = 111101₂

33₈ = 3*8⁰ + 3*8¹ = 27₁₀

117₈ = 7*8⁰ + 1*8¹ + 1*8² = 79₁₀

106₁₀ = 2*8⁰ + 5*8¹ + 1*8² = 152₈

72₈ = 2*8⁰ + 7*8¹ = 58₁₀

46₈ = 6*8⁰ + 4*8¹ = 38₁₀

20₁₀ = 4*8⁰ + 2*8¹ = 24₈

2F₁₆ = F*16⁰ + 2*16¹ = 47₁₀

D1₁₆ = 1*16⁰ + D*16¹ = 209₁₀

256₁₀ = 0*16⁰ + 0*16¹ + 1*16² = 100₁₆

FD₁₆ = D*16⁰ + F*16¹ = 253₁₀

AF₁₆ = F*16⁰ + A*16¹ = 175₁₀

78₁₀ = 14*16⁰ + 4*16¹ = 4E₁₆
