Yechim qadamlari

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

$$4+16+\frac{-3}{2!}\times 4+\frac{-4}{3!}\times 8$$

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

$$20+\frac{-3}{2!}\times 4+\frac{-4}{3!}\times 8$$

2 ning faktoriali 2 ga teng.

$$20+\frac{-3}{2}\times 4+\frac{-4}{3!}\times 8$$

\frac{-3}{2} kasri manfiy belgini olib tashlash bilan -\frac{3}{2} sifatida qayta yozilishi mumkin.

$$20-\frac{3}{2}\times 4+\frac{-4}{3!}\times 8$$

-\frac{3}{2}\times 4 ni yagona kasrga aylantiring.

$$20+\frac{-3\times 4}{2}+\frac{-4}{3!}\times 8$$

-12 hosil qilish uchun -3 va 4 ni ko'paytirish.

$$20+\frac{-12}{2}+\frac{-4}{3!}\times 8$$

-6 ni olish uchun -12 ni 2 ga bo‘ling.

$$20-6+\frac{-4}{3!}\times 8$$

14 olish uchun 20 dan 6 ni ayirish.

$$14+\frac{-4}{3!}\times 8$$

3 ning faktoriali 6 ga teng.

$$14+\frac{-4}{6}\times 8$$

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

$$14-\frac{2}{3}\times 8$$

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

$$14+\frac{-2\times 8}{3}$$

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

$$14+\frac{-16}{3}$$

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

$$14-\frac{16}{3}$$

14 ni \frac{42}{3} kasrga o‘giring.

$$\frac{42}{3}-\frac{16}{3}$$

\frac{42}{3} va \frac{16}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{42-16}{3}$$

26 olish uchun 42 dan 16 ni ayirish.

$$\frac{26}{3}$$

Omil

$$\frac{2 \cdot 13}{3} = 8\frac{2}{3} = 8,666666666666666$$
