$$\frac { - 3 ^ { 2 } + ( 4 - 9 ) ^ { 2 } } { 7 - 2 \cdot 6 }$$

Baholash

$$-\frac{16}{5}=-3,2$$

Yechim qadamlari

2 daraja ko‘rsatkichini 3 ga hisoblang va 9 ni qiymatni oling.

$$\frac{-9+\left(4-9\right)^{2}}{7-2\times 6}$$

-5 olish uchun 4 dan 9 ni ayirish.

$$\frac{-9+\left(-5\right)^{2}}{7-2\times 6}$$

2 daraja ko‘rsatkichini -5 ga hisoblang va 25 ni qiymatni oling.

$$\frac{-9+25}{7-2\times 6}$$

16 olish uchun -9 va 25'ni qo'shing.

$$\frac{16}{7-2\times 6}$$

12 hosil qilish uchun 2 va 6 ni ko'paytirish.

$$\frac{16}{7-12}$$

-5 olish uchun 7 dan 12 ni ayirish.

$$\frac{16}{-5}$$

\frac{16}{-5} kasri manfiy belgini olib tashlash bilan -\frac{16}{5} sifatida qayta yozilishi mumkin.

$$-\frac{16}{5}$$

Omil

$$-\frac{16}{5} = -3\frac{1}{5} = -3,2$$
