Yechim qadamlari

25 ni olish uchun 50 ni 2 ga bo‘ling.

$$\frac{\left(-35+25\right)^{2}}{1}-101+\sqrt{9\times 2+7}$$

-10 olish uchun -35 va 25'ni qo'shing.

$$\frac{\left(-10\right)^{2}}{1}-101+\sqrt{9\times 2+7}$$

2 daraja ko‘rsatkichini -10 ga hisoblang va 100 ni qiymatni oling.

$$\frac{100}{1}-101+\sqrt{9\times 2+7}$$

Har qanday son birga bo‘linganda, natija o‘zi chiqadi.

$$100-101+\sqrt{9\times 2+7}$$

-1 olish uchun 100 dan 101 ni ayirish.

$$-1+\sqrt{9\times 2+7}$$

18 hosil qilish uchun 9 va 2 ni ko'paytirish.

$$-1+\sqrt{18+7}$$

25 olish uchun 18 va 7'ni qo'shing.

$$-1+\sqrt{25}$$

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

$$-1+5$$

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