Question

Помогите решить информатику!!! 8 класс

Answer 1

Ответ:

2573₁₀ = 3*10⁰ + 7*10¹ + 5*10² + 2*10³

1010101₂ = 1*2⁰ + 0*2¹ + 1*2² + 0*2³ + 1*2⁴ + 0*2⁵ + 1*2⁶

95₁₀ = 1011111₂ = 137₈

E2₁₆ = 11100010₂

11111101001₂  + 1110000111₂ = 101101110000₂

11101₂ - 10011₂ =   1010₂

10111₂ * 101₂ = 1110011₂

Объяснение:

95₁₀ = 1*2⁰ + 1*2¹ + 1*2² + 1*2³ + 1*2⁴ + 0*2⁵ + 1*2⁶ = 1011111₂

95₁₀ = 7*8⁰ + 3*8¹ + 1*8² = 137₈

E2₁₆ = 2*16⁰ + E*16¹ = 226₁₀

226₁₀ = 0*2⁰ + 1*2¹ + 0*2² + 0*2³ + 0*2⁴ + 1*2⁵ + 1*2⁶ + 1*2⁷ = 11100010₂

11111101001₂ = 1*2⁰ + 0*2¹ + 0*2² + 1*2³ + 0*2⁴ + 1*2⁵ + 1*2⁶ + 1*2⁷ + 1*2⁸ + 1*2⁹ + 1*2¹⁰ = 2025₁₀

1110000111₂ = 1*2⁰ + 1*2¹ + 1*2² + 0*2³ + 0*2⁴ + 0*2⁵ + 0*2⁶ + 1*2⁷ + 1*2⁸ + 1*2⁹ = 903₁₀

2928₁₀ = 0*2⁰ + 0*2¹ + 0*2² + 0*2³ + 1*2⁴ + 1*2⁵ + 1*2⁶ + 0*2⁷ + 1*2⁸ + 1*2⁹ + 0*2¹⁰ + 1*2¹¹ = 101101110000₂

11101₂ = 1*2⁰ + 0*2¹ + 1*2² + 1*2³ + 1*2⁴ = 29₁₀

10011₂ = 1*2⁰ + 1*2¹ + 0*2² + 0*2³ + 1*2⁴ = 19₁₀

10₁₀ = 0*2⁰ + 1*2¹ + 0*2² + 1*2³ = 1010₂

10111₂ = 1*2⁰ + 1*2¹ + 1*2² + 0*2³ + 1*2⁴ = 23₁₀

101₂ = 1*2⁰ + 0*2¹ + 1*2² = 5₁₀

115₁₀ = 1*2⁰ + 1*2¹ + 0*2² + 0*2³ + 1*2⁴ + 1*2⁵ + 1*2⁶ = 1110011₂
