-3157,8

Объяснение:

23А_16 + 111001_2 * (21_16 - 550_8) / 101_2 = 570 + 57 * (33 - 360) / 5 = 570 + 57 * (-327) / 5 = 570 + (-18639) / 5 = 570 + (-3727,8) = -3157,8

23А_16 = 2 * 16^2 + 3 * 16^1 + 10 * 16^0 = 512 + 48 + 10 = 570_10

111001_2 = 1 * 2^5 + 1 * 2^4 + 1 * 2^3 + 0 * 2^2 + 0 * 2^1 + 1 * 2^0 = 32 + 16 + 8 + 0 + 0 + 1 = 57_10

21_16 = 2 * 16^1 + 1 * 16^0 = 32 + 1 = 33_10

550_8 = 5 * 8^2 + 5 * 8^1 + 0 * 8^0 = 320 + 40 + 0 = 360_10

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