Your answer :

897₁₀ = 1, 601₈ 539₁₀ = 1, 033₈ 246₁₀ = 366₈ ⎫⎪⎬⎪⎭ This set contains a mistake.

Well, let’s check:

0 , r = 1 8)1 , r = 6 8)14 , r = 0 8)112 , r = 1 8)897 so, 897 = 1, 601₈; 0 , r = 1 8)1 , r = 0 8)8 , r = 3 8)67 , r = 3 8)539 so, 539₁₀ = 1, 033₈; 0 , r = 3 8)3 , r = 6 8)30 , r = 6 8)246 so, 246₁₀ = 366₈.

They’re all correct. Now return to Page 237 and try again.
