Answer

Tengsizlikning yechimi bo'ladigan oraliqlarning uzunliklari yig'indisi 8 ga teng.

Solution

Berilgan tengsizlikni quyidagicha yechamiz: \[ \frac{x^{2}-9}{|x^{2}-9|} + \frac{|49 - x^{2}|}{49 - x^{2}} \geq 2 \] **Tengsizlikni yechish jarayoni:** 1. **Shartlarni aniqlash:** - \( x^{2} - 9 > 0 \) \(\Rightarrow |x| > 3 \) - \( x^{2} - 49 > 0 \) \(\Rightarrow |x| > 7 \) - \( x^{2} - 9 < 0 \) \(\Rightarrow |x| < 3 \) - \( x^{2} - 49 < 0 \) \(\Rightarrow |x| < 7 \) 2. **Interval bo‘yicha tahlil qilish:** - **\( |x| > 7 \) (ya’ni, \( x < -7 \) yoki \( x > 7 \)):** \[ \frac{x^{2}-9}{|x^{2}-9|} = 1, \quad \frac{|49 - x^{2}|}{49 - x^{2}} = -1 \] Demak: \( 1 + (-1) = 0 \geq 2 \) — **Noto‘g‘ri** - **\( 3 < |x| < 7 \) (ya’ni, \( -7 < x < -3 \) yoki \( 3 < x < 7 \)):** \[ \frac{x^{2}-9}{|x^{2}-9|} = 1, \quad \frac{|49 - x^{2}|}{49 - x^{2}} = 1 \] Demak: \( 1 + 1 = 2 \geq 2 \) — **To‘g‘ri** - **\( |x| < 3 \) (ya’ni, \( -3 < x < 3 \)):** \[ \frac{x^{2}-9}{|x^{2}-9|} = -1, \quad \frac{|49 - x^{2}|}{49 - x^{2}} = 1 \] Demak: \( -1 + 1 = 0 \geq 2 \) — **Noto‘g‘ri** 3. **Yechim oraliqlari:** - \( -7 < x < -3 \) - \( 3 < x < 7 \) 4. **Oraliqlarning uzunliklari:** - Har bir interval uzunligi \( 7 - 3 = 4 \) - Ikkala intervalning yig‘indisi: \( 4 + 4 = 8 \) **Natija:** Tengsizlikning yechimi bo‘ladigan oraliqlarning uzunliklari yig‘indisi **8** ga teng.

Aziz matematik qiziqishlilar, keling, ushbu tenglama va tengsizliklar bilan bog'liq bir qator qiziqarli ma'lumotlarni ko'rib chiqamiz! O'tgan asrlarda matematikalar, avvalgi oddiy ko'rinishdan ekstravagant formulalar va murakkab tenglamalarga o'tish uchun tanaffus qildi. Bir vaqtlar, avvalgi matematik qoidalar faqat oddiy slayderlar, olma va apelsinlar raqobatlashadigan masalalarda hamda qadimiy yunonlar davridagi akademiyalarda satanalar va geometriya asoslarini o'rganish uchun ishlatilardi. Bu sodda qoidalar ular matematik ijodchiligini rivojlantirishda o'ziga xos yo'l ochdi! Tengsizliklar va tenglamalar bugungi kunda qanday qo'llanilayotganini tasavvur qilishingiz mumkin: algebra, fizika, iqtisodiyot va boshqa ko'plab sohalarda. Masalan, iqtisodiy modellarda bunday tenglamalardan foydalangan holda resurslarni taqsimlashning eng samarali usullarini topish mumkin. Keling, shuni eslatib o'tamizki, matematik muammolarni hal qilishda algoritmlardan foydalanish bizga tez, aniq va samarali yechimlar ko'rsatishga yordam beradi!
