A) 165; 175;

B) 175; 385;

C) 165;

D) 175;

E) 385?

Решение. №12 (с. 76)
Алгебра, 10 класс Учебник, авторы: Абылкасымова Алма Есимбековна, Жумагулова Зауре Абдыкеновна, издательство Мектеп, Алматы, 2019, страница 76, номер 12, Решение
Решение 2. №12 (с. 76)

Для решения этой задачи необходимо разложить каждое из предложенных чисел (165, 175, 385) на простые множители и проверить, удовлетворяют ли эти множители трем условиям:

1. Все множители — простые числа.

2. Все множители — различные (не повторяются).

3. Все множители — больше 3.

Анализ числа 165

Разложим число 165 на простые множители. Поскольку число оканчивается на 5, оно делится на 5:

$165 : 5 = 33$

Число 33 делится на 3:

$33 : 3 = 11$

11 — простое число. Таким образом, разложение числа 165 имеет вид:

$165 = 3 \cdot 5 \cdot 11$

Множители (3, 5, 11) являются простыми и различными. Однако множитель 3 не удовлетворяет условию "быть больше числа 3". Следовательно, число 165 не подходит.

Анализ числа 175

Разложим число 175 на простые множители. Оно также оканчивается на 5:

$175 : 5 = 35$

Число 35 также делится на 5:

$35 : 5 = 7$

7 — простое число. Таким образом, разложение числа 175 имеет вид:

$175 = 5 \cdot 5 \cdot 7 = 5^2 \cdot 7$

Множители (5, 7) больше 3. Однако множители не являются различными, так как число 5 повторяется дважды. Следовательно, число 175 не подходит.

Анализ числа 385

Разложим число 385 на простые множители. Оно оканчивается на 5:

$385 : 5 = 77$

Число 77 делится на 7:

$77 : 7 = 11$

11 — простое число. Таким образом, разложение числа 385 имеет вид:

$385 = 5 \cdot 7 \cdot 11$

Проверим условия для множителей (5, 7, 11):

- Они являются простыми числами. (Верно)

- Они являются различными. (Верно)

- Все они больше 3 ( $5>3$, $7>3$, $11>3$ ). (Верно)

Число 385 удовлетворяет всем условиям задачи.

Таким образом, из трех чисел только 385 можно представить в виде произведения простых различных чисел, больших числа 3. Это соответствует варианту ответа E).

Ответ: E) 385?
