a) (1111101₂ + AF₁₆) : 36₈
1111101₂ = 1*2^6 + 1*2^5 + 1*2^4 + 1*2^3 + 1*2^2 + 0*2^1 + 1*2^0 = 64 + 32 + 16 + 8 + 4 + 1 = 125₁₀
AF₁₆ = 10*16^1 + 15*16^0 = 160 + 15 = 175₁₀
36₈ = 3*8^1 + 6*8^0 = 24 + 6 = 30₁₀
(125 + 175) : 30 = 300 : 30 = 10
Ответ: 10
б) 125₈ + 101₂ * 2A₁₆ - 141₈
125₈ = 1*8^2 + 2*8^1 + 5*8^0 = 64 + 16 + 5 = 85₁₀
101₂ = 1*2^2 + 0*2^1 + 1*2^0 = 4 + 1 = 5₁₀
2A₁₆ = 2*16^1 + 10*16^0 = 32 + 10 = 42₁₀
141₈ = 1*8^2 + 4*8^1 + 1*8^0 = 64 + 32 + 1 = 97₁₀
85 + 5 * 42 - 97 = 85 + 210 - 97 = 295 - 97 = 198
