А = 4 * 16¹ + 3 * 16⁰ = 4 * 16 + 3 * 1 = 64 + 3 = 67
В = 1 * 8² + 0 * 8¹ + 7 * 8⁰ = 1 * 64 + 0 * 8 + 7 * 1 = 64 + 0 + 7 = 71
С = 1 * 2⁶ + 0 * 2⁵ + 0 * 2⁴ + 0 * 2³ + 1 * 2² + 0 * 2¹ + 1 * 2⁰ = 1 * 64 + 0 * 32 + 0 * 16 + 0 * 8 + 1 * 4 + 0 * 2 + 1 * 1 = 64 + 0 + 0 + 0 + 4 + 0 + 1 = 69
A = 67, B = 71, C = 69
В порядке возрастания: A, C, B
