Tasdiqlamoq

Yechim qadamlari

Tenglamaning ikkala tarafini 160 ga, 160,4 ning eng kichik karralisiga ko‘paytiring. 160 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$160\left(320^{2}-160^{2}\right)\times \frac{1}{160}\geq 40\left(1\times 4+1\right)$$

2 daraja ko‘rsatkichini 320 ga hisoblang va 102400 ni qiymatni oling.

$$160\left(102400-160^{2}\right)\times \frac{1}{160}\geq 40\left(1\times 4+1\right)$$

2 daraja ko‘rsatkichini 160 ga hisoblang va 25600 ni qiymatni oling.

$$160\left(102400-25600\right)\times \frac{1}{160}\geq 40\left(1\times 4+1\right)$$

76800 olish uchun 102400 dan 25600 ni ayirish.

$$160\times 76800\times \frac{1}{160}\geq 40\left(1\times 4+1\right)$$

12288000 hosil qilish uchun 160 va 76800 ni ko'paytirish.

$$12288000\times \frac{1}{160}\geq 40\left(1\times 4+1\right)$$

\frac{12288000}{160} hosil qilish uchun 12288000 va \frac{1}{160} ni ko'paytirish.

$$\frac{12288000}{160}\geq 40\left(1\times 4+1\right)$$

76800 ni olish uchun 12288000 ni 160 ga bo‘ling.

$$76800\geq 40\left(1\times 4+1\right)$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$76800\geq 40\left(4+1\right)$$

5 olish uchun 4 va 1'ni qo'shing.

$$76800\geq 40\times 5$$

200 hosil qilish uchun 40 va 5 ni ko'paytirish.

$$76800\geq 200$$

76800 va 200 ni taqqoslang.
