Ответ:

78

Объяснение:

Переведем числа в десятичную систему счисления:

70_8 = 0 * 8^0 + 7 * 8 ^ 1 = 0 + 56 = 56\\\\10111_2 = 1 * 2 ^ 0 + 1 * 2 ^ 1 + 1 * 2 ^ 2 + 0 * 2 ^ 3 + 1 * 2 ^ 4 = 1 + 2 + 4 + 0 + 16 = 23\\\\ 4E_{16} = E * 16 ^ 0 + 4 * 16 ^ 1 = [A_{16} = 10,B_{16} = 11,C_{16} = 12,D_{16} = 13,E_{16} = 14, F_{16} = 15] = 14 + 64 = 78

Получили, что наибольшее из 3-х чисел 4E_{16} = 78_{10}
