5+((3/5)(-7))-(-1-8) eching

$$5 + ( ( 3 / 5 ) ( - 7 ) ) - ( - 1 - 8 )$$

Baholash

$$\frac{49}{5}=9,8$$

Yechim qadamlari

\frac{3}{5}\left(-7\right) ni yagona kasrga aylantiring.

$$5+\frac{3\left(-7\right)}{5}-\left(-1-8\right)$$

-21 hosil qilish uchun 3 va -7 ni ko'paytirish.

$$5+\frac{-21}{5}-\left(-1-8\right)$$

\frac{-21}{5} kasri manfiy belgini olib tashlash bilan -\frac{21}{5} sifatida qayta yozilishi mumkin.

$$5-\frac{21}{5}-\left(-1-8\right)$$

5 ni \frac{25}{5} kasrga o‘giring.

$$\frac{25}{5}-\frac{21}{5}-\left(-1-8\right)$$

\frac{25}{5} va \frac{21}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{25-21}{5}-\left(-1-8\right)$$

4 olish uchun 25 dan 21 ni ayirish.

$$\frac{4}{5}-\left(-1-8\right)$$

-9 olish uchun -1 dan 8 ni ayirish.

$$\frac{4}{5}-\left(-9\right)$$

-9 ning teskarisi 9 ga teng.

$$\frac{4}{5}+9$$

9 ni \frac{45}{5} kasrga o‘giring.

$$\frac{4}{5}+\frac{45}{5}$$

\frac{4}{5} va \frac{45}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{4+45}{5}$$

49 olish uchun 4 va 45'ni qo'shing.

$$\frac{49}{5}$$

Omil

$$\frac{7 ^ {2}}{5} = 9\frac{4}{5} = 9,8$$
