Yechim qadamlari

-3 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{8} ni qiymatni oling.

$$\frac{1}{\frac{1}{8}}-\frac{1}{2^{-1}}$$

1 ni \frac{1}{8} ga bo'lish 1 ga k'paytirish \frac{1}{8} ga qaytarish.

$$1\times 8-\frac{1}{2^{-1}}$$

8 hosil qilish uchun 1 va 8 ni ko'paytirish.

$$8-\frac{1}{2^{-1}}$$

-1 daraja ko‘rsatkichini 2 ga hisoblang va \frac{1}{2} ni qiymatni oling.

$$8-\frac{1}{\frac{1}{2}}$$

1 ni \frac{1}{2} ga bo'lish 1 ga k'paytirish \frac{1}{2} ga qaytarish.

$$8-1\times 2$$

2 hosil qilish uchun 1 va 2 ni ko'paytirish.

$$8-2$$

6 olish uchun 8 dan 2 ni ayirish.
