Yechim qadamlari

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$\sqrt{4+9^{2}+15}+\sqrt{25}-\sqrt{36}$$

2 daraja ko‘rsatkichini 9 ga hisoblang va 81 ni qiymatni oling.

$$\sqrt{4+81+15}+\sqrt{25}-\sqrt{36}$$

85 olish uchun 4 va 81'ni qo'shing.

$$\sqrt{85+15}+\sqrt{25}-\sqrt{36}$$

100 olish uchun 85 va 15'ni qo'shing.

$$\sqrt{100}+\sqrt{25}-\sqrt{36}$$

100 ning kvadrat ildizini hisoblab, 10 natijaga ega bo‘ling.

$$10+\sqrt{25}-\sqrt{36}$$

25 ning kvadrat ildizini hisoblab, 5 natijaga ega bo‘ling.

$$10+5-\sqrt{36}$$

15 olish uchun 10 va 5'ni qo'shing.

$$15-\sqrt{36}$$

36 ning kvadrat ildizini hisoblab, 6 natijaga ega bo‘ling.

$$15-6$$

9 olish uchun 15 dan 6 ni ayirish.

$$9$$

Omil
