157₈ = 111₁₀
3DB₁₆ = 987₁₀
130₁₀ = 10000010₂
130₁₀ = 202₈
130₁₀ = 82₁₆
Объяснение:
11011011₂ = 1*2⁰ + 1*2¹ + 0*2² + 1*2³ + 1*2⁴ + 0*2⁵ + 1*2⁶ + 1*2⁷ = 219₁₀
157₈ = 7*8⁰ + 5*8¹ + 1*8² = 111₁₀
3DB₁₆ = 11*16⁰ + 13*16¹ + 3*16² = 987₁₀
130₁₀ = 0*2⁰ + 1*2¹ + 0*2² + 0*2³ + 0*2⁴ + 0*2⁵ + 0*2⁶ + 1*2⁷ = 10000010₂
130₁₀ = 2*8⁰ + 0*8¹ + 2*8² = 202₈
130₁₀ = 2*16⁰ + 8*16¹ = 82₁₆
