Answer 1

Ответ:

a) 10

б) 198

Объяснение:

a) (1111101_2 + AF_16) / 36_8 = (125 + 175) / 30 = 300 / 30 = 10

1111101_2 = 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 + 0 + 1 = 125_10

AF_16 = 10 * 16^1 + 15 * 16^0 = 160 + 15 = 175_10

36_8 = 3 * 8^1 + 6 * 8^0 = 24 + 6 = 30_10

б) 125_8 + 101_2 * 2A_16 - 141_8 = 85 + 5 * 42 - 97 = 85 + 210 - 97 = 198

125_8 = 1 * 8^2 + 2 * 8^1 + 5 * 8^0 = 64 + 16 + 5 = 85_10

101_2 = 1 * 2^2 + 0 * 2^1 + 1 * 2^0 = 4 + 0 + 1 = 5_10

2A_16 = 2 * 16^1 + 10 * 16_0 = 32 + 10 = 42_10

141_8 = 1 * 8^2 + 4 * 8^1 + 1 * 8^0 = 64 + 32 + 1 = 97_10
