Yechim qadamlari

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

$$\frac{13}{25}+\frac{1}{52}$$

25 va 52 ning eng kichik umumiy karralisi 1300 ga teng. \frac{13}{25} va \frac{1}{52} ni 1300 maxraj bilan kasrlarga aylantirib oling.

$$\frac{676}{1300}+\frac{25}{1300}$$

\frac{676}{1300} va \frac{25}{1300} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{676+25}{1300}$$

701 olish uchun 676 va 25'ni qo'shing.

$$\frac{701}{1300}$$

Omil

$$\frac{701}{2 ^ {2} \cdot 5 ^ {2} \cdot 13} = 0,5392307692307692$$
