Yechim qadamlari

2 daraja ko‘rsatkichini 17 ga hisoblang va 289 ni qiymatni oling.

$$\sqrt{289-\frac{\left(40-10\right)^{2}}{4}}$$

30 olish uchun 40 dan 10 ni ayirish.

$$\sqrt{289-\frac{30^{2}}{4}}$$

2 daraja ko‘rsatkichini 30 ga hisoblang va 900 ni qiymatni oling.

$$\sqrt{289-\frac{900}{4}}$$

225 ni olish uchun 900 ni 4 ga bo‘ling.

$$\sqrt{289-225}$$

64 olish uchun 289 dan 225 ni ayirish.

$$\sqrt{64}$$

64 ning kvadrat ildizini hisoblab, 8 natijaga ega bo‘ling.
