Ответ:Для оцінки виразу 0.25(ab), де 4 < a < 6 і 2 < b < 10, спочатку розглянемо найменше можливі значення a і b, а потім найбільше можливі значення a і b, і обчислимо вираз у кожному з цих випадків.

Мінімальні значення:

Найменше можливе значення a = 4.

Найменше можливе значення b = 2.

Тоді вираз 0.25(ab) при мінімальних значеннях a і b дорівнює:

0.25(4 * 2) = 0.25 * 8 = 2.

Максимальні значення:

Найбільше можливе значення a = 6.

Найбільше можливе значення b = 10.

Тоді вираз 0.25(ab) при максимальних значеннях a і b дорівнює:

0.25(6 * 10) = 0.25 * 60 = 15.

Отже, значення виразу 0.25(ab) в діапазоні, коли 4 < a < 6 і 2 < b < 10, може змінюватися від 2 до 15.
