Answer 1

Answer:

348₍₈₎

= (3 × 8²) + (4 × 8¹) + (8 × 8⁰)

= (3 × 64) + (4 × 8) + (8 × 1)

= 192 + 32 + 8

= 232₍₁₀₎

668₍₈₎

= (6 × 8²) + (6 × 8¹) + (8 × 8⁰)

= (6 × 64) + (6 × 8) + (8 × 1)

= 384 + 48 + 8

= 440₍₁₀₎

908₍₈₎

= (9 × 8²) + (0 × 8¹) + (8 × 8⁰)

= (9 × 64) + (0 × 8) + (8 × 1)

= 576 + 0 + 8

= 584₍₁₀₎

1008₍₈₎

= (1 × 8³) + (0 × 8²) + (0 × 8¹) + (8 × 8⁰)

= (1 × 512) + (0 × 64) + (0 × 8) + (8 × 1)

= 512 + 0 + 0 + 8

= 520₍₁₀₎

218₍₈₎

= (2 × 8²) + (1 × 8¹) + (8 × 8⁰)

= (2 × 64) + (1 × 8) + (8 × 1)

= 128 + 8 + 8

= 144₍₁₀₎
