Yechim qadamlari

2 daraja ko‘rsatkichini 6 ga hisoblang va 36 ni qiymatni oling.

$$\frac{36}{6^{2}-4}-\frac{1}{6-2}$$

2 daraja ko‘rsatkichini 6 ga hisoblang va 36 ni qiymatni oling.

$$\frac{36}{36-4}-\frac{1}{6-2}$$

32 olish uchun 36 dan 4 ni ayirish.

$$\frac{36}{32}-\frac{1}{6-2}$$

\frac{36}{32} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{8}-\frac{1}{6-2}$$

4 olish uchun 6 dan 2 ni ayirish.

$$\frac{9}{8}-\frac{1}{4}$$

8 va 4 ning eng kichik umumiy karralisi 8 ga teng. \frac{9}{8} va \frac{1}{4} ni 8 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{8}-\frac{2}{8}$$

\frac{9}{8} va \frac{2}{8} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-2}{8}$$

7 olish uchun 9 dan 2 ni ayirish.

$$\frac{7}{8}$$
