Yechim qadamlari

6 daraja ko‘rsatkichini -2 ga hisoblang va 64 ni qiymatni oling.

$$\frac{\frac{64}{2^{3}}+\frac{\left(-3\right)^{4}}{3^{2}}}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

$$\frac{\frac{64}{8}+\frac{\left(-3\right)^{4}}{3^{2}}}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

8 ni olish uchun 64 ni 8 ga bo‘ling.

$$\frac{8+\frac{\left(-3\right)^{4}}{3^{2}}}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

4 daraja ko‘rsatkichini -3 ga hisoblang va 81 ni qiymatni oling.

$$\frac{8+\frac{81}{3^{2}}}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

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

$$\frac{8+\frac{81}{9}}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

9 ni olish uchun 81 ni 9 ga bo‘ling.

$$\frac{8+9}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

17 olish uchun 8 va 9'ni qo'shing.

$$\frac{17}{3-20}-\frac{2^{7}}{\left(-2\right)^{4}}$$

-17 olish uchun 3 dan 20 ni ayirish.

$$\frac{17}{-17}-\frac{2^{7}}{\left(-2\right)^{4}}$$

-1 ni olish uchun 17 ni -17 ga bo‘ling.

$$-1-\frac{2^{7}}{\left(-2\right)^{4}}$$

7 daraja ko‘rsatkichini 2 ga hisoblang va 128 ni qiymatni oling.

$$-1-\frac{128}{\left(-2\right)^{4}}$$

4 daraja ko‘rsatkichini -2 ga hisoblang va 16 ni qiymatni oling.

$$-1-\frac{128}{16}$$

8 ni olish uchun 128 ni 16 ga bo‘ling.

$$-1-8$$

-9 olish uchun -1 dan 8 ni ayirish.
