Yechim qadamlari

14 hosil qilish uchun 7 va 2 ni ko'paytirish.

$$7+14+\frac{-3}{2!}\times 4+\frac{-5}{3!}\times 2^{3}$$

21 olish uchun 7 va 14'ni qo'shing.

$$21+\frac{-3}{2!}\times 4+\frac{-5}{3!}\times 2^{3}$$

2 ning faktoriali 2 ga teng.

$$21+\frac{-3}{2}\times 4+\frac{-5}{3!}\times 2^{3}$$

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

$$21-\frac{3}{2}\times 4+\frac{-5}{3!}\times 2^{3}$$

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

$$21+\frac{-3\times 4}{2}+\frac{-5}{3!}\times 2^{3}$$

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

$$21+\frac{-12}{2}+\frac{-5}{3!}\times 2^{3}$$

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

$$21-6+\frac{-5}{3!}\times 2^{3}$$

15 olish uchun 21 dan 6 ni ayirish.

$$15+\frac{-5}{3!}\times 2^{3}$$

3 ning faktoriali 6 ga teng.

$$15+\frac{-5}{6}\times 2^{3}$$

\frac{-5}{6} kasri manfiy belgini olib tashlash bilan -\frac{5}{6} sifatida qayta yozilishi mumkin.

$$15-\frac{5}{6}\times 2^{3}$$

3 daraja ko‘rsatkichini 2 ga hisoblang va 8 ni qiymatni oling.

$$15-\frac{5}{6}\times 8$$

-\frac{5}{6}\times 8 ni yagona kasrga aylantiring.

$$15+\frac{-5\times 8}{6}$$

-40 hosil qilish uchun -5 va 8 ni ko'paytirish.

$$15+\frac{-40}{6}$$

\frac{-40}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$15-\frac{20}{3}$$

15 ni \frac{45}{3} kasrga o‘giring.

$$\frac{45}{3}-\frac{20}{3}$$

\frac{45}{3} va \frac{20}{3} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{45-20}{3}$$

25 olish uchun 45 dan 20 ni ayirish.

$$\frac{25}{3}$$

Omil

$$\frac{5 ^ {2}}{3} = 8\frac{1}{3} = 8,333333333333334$$
