Verified answer

Ответ:

5. 417₈ + CA₁₆  = 731₈

6. 13₉

Объяснение:

5.

417₈ = 7*8⁰ + 1*8¹ + 4*8² = 271₁₀

CA₁₆ = A*16⁰ + C*16¹ = 202₁₀

473₁₀ = 1*8⁰ + 3*8¹ + 7*8² = 731₈

8.

12₁₀ = 0*2⁰ + 0*2¹ + 1*2² + 1*2³ = 1100₂

12₁₀ = 0*3⁰ + 1*3¹ + 1*3² = 110₃

12₁₀ = 0*4⁰ + 3*4¹ = 30₄

12₁₀ = 2*5⁰ + 2*5¹ = 22₅

12₁₀ = 0*6⁰ + 2*6¹ = 20₆

12₁₀ = 5*7⁰ + 1*7¹ = 15₇

12₁₀ = 4*8⁰ + 1*8¹ = 14₈

12₁₀ = 3*9⁰ + 1*9¹ = 13₉

12₁₀ = 1*11⁰ + 1*11¹ = 11₁₁

12₁₀ = 0*12⁰ + 1*12¹ = 10₁₂

12₁₀ = 12*13⁰ = C₁₃

12₁₀ = 12*14⁰ = C₁₄

12₁₀ = 12*15⁰ = C₁₅

12₁₀ = 12*16⁰ = C₁₆
