Объяснение:
121₁₀ = 1*2⁰ + 0*2¹ + 0*2² + 1*2³ + 1*2⁴ + 1*2⁵ + 1*2⁶ = 1111001₂
121₁₀ = 1*8⁰ + 7*8¹ + 1*8² = 171₈
121₁₀ = 9*16⁰ + 7*16¹ = 79₁₆
304₁₀ = 0*2⁰ + 0*2¹ + 0*2² + 0*2³ + 1*2⁴ + 1*2⁵ + 0*2⁶ + 0*2⁷ + 1*2⁸ = 100110000₂
304₁₀ = 0*8⁰ + 6*8¹ + 4*8² = 460₈
304₁₀ = 0*16⁰ + 3*16¹ + 1*16² = 130₁₆
62₁₀ = 0*2⁰ + 1*2¹ + 1*2² + 1*2³ + 1*2⁴ + 1*2⁵ = 111110₂
62₁₀ = 6*8⁰ + 7*8¹ = 76₈
62₁₀ = 14*16⁰ + 3*16¹ = 3E₁₆
