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

$$4+\frac{4}{2}=7^{-2}$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$4+2=7^{-2}$$

6 olish uchun 4 va 2'ni qo'shing.

$$6=7^{-2}$$

-2 daraja ko‘rsatkichini 7 ga hisoblang va \frac{1}{49} ni qiymatni oling.

$$6=\frac{1}{49}$$

6 ni \frac{294}{49} kasrga o‘giring.

$$\frac{294}{49}=\frac{1}{49}$$

\frac{294}{49} va \frac{1}{49} ni taqqoslang.
