Yechim qadamlari

16 hosil qilish uchun 8 va 2 ni ko'paytirish.

$$4+16+\frac{-3}{21}\times 4+\frac{-4}{3!}\times 8$$

20 olish uchun 4 va 16'ni qo'shing.

$$20+\frac{-3}{21}\times 4+\frac{-4}{3!}\times 8$$

\frac{-3}{21} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$20-\frac{1}{7}\times 4+\frac{-4}{3!}\times 8$$

-\frac{1}{7}\times 4 ni yagona kasrga aylantiring.

$$20+\frac{-4}{7}+\frac{-4}{3!}\times 8$$

\frac{-4}{7} kasri manfiy belgini olib tashlash bilan -\frac{4}{7} sifatida qayta yozilishi mumkin.

$$20-\frac{4}{7}+\frac{-4}{3!}\times 8$$

20 ni \frac{140}{7} kasrga o‘giring.

$$\frac{140}{7}-\frac{4}{7}+\frac{-4}{3!}\times 8$$

\frac{140}{7} va \frac{4}{7} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{140-4}{7}+\frac{-4}{3!}\times 8$$

136 olish uchun 140 dan 4 ni ayirish.

$$\frac{136}{7}+\frac{-4}{3!}\times 8$$

3 ning faktoriali 6 ga teng.

$$\frac{136}{7}+\frac{-4}{6}\times 8$$

\frac{-4}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{136}{7}-\frac{2}{3}\times 8$$

-\frac{2}{3}\times 8 ni yagona kasrga aylantiring.

$$\frac{136}{7}+\frac{-2\times 8}{3}$$

-16 hosil qilish uchun -2 va 8 ni ko'paytirish.

$$\frac{136}{7}+\frac{-16}{3}$$

\frac{-16}{3} kasri manfiy belgini olib tashlash bilan -\frac{16}{3} sifatida qayta yozilishi mumkin.

$$\frac{136}{7}-\frac{16}{3}$$

7 va 3 ning eng kichik umumiy karralisi 21 ga teng. \frac{136}{7} va \frac{16}{3} ni 21 maxraj bilan kasrlarga aylantirib oling.

$$\frac{408}{21}-\frac{112}{21}$$

\frac{408}{21} va \frac{112}{21} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{408-112}{21}$$

296 olish uchun 408 dan 112 ni ayirish.

$$\frac{296}{21}$$

Omil

$$\frac{2 ^ {3} \cdot 37}{3 \cdot 7} = 14\frac{2}{21} = 14,095238095238095$$
