Baholash

$$-\frac{7}{64}=-0,109375$$

Yechim qadamlari

\frac{-7}{40} kasri manfiy belgini olib tashlash bilan -\frac{7}{40} sifatida qayta yozilishi mumkin.

$$5\left(-\frac{7}{40}\right)+\left(\frac{7}{8}\right)^{2}$$

5\left(-\frac{7}{40}\right) ni yagona kasrga aylantiring.

$$\frac{5\left(-7\right)}{40}+\left(\frac{7}{8}\right)^{2}$$

-35 hosil qilish uchun 5 va -7 ni ko'paytirish.

$$\frac{-35}{40}+\left(\frac{7}{8}\right)^{2}$$

\frac{-35}{40} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{7}{8}+\left(\frac{7}{8}\right)^{2}$$

2 daraja ko‘rsatkichini \frac{7}{8} ga hisoblang va \frac{49}{64} ni qiymatni oling.

$$-\frac{7}{8}+\frac{49}{64}$$

8 va 64 ning eng kichik umumiy karralisi 64 ga teng. -\frac{7}{8} va \frac{49}{64} ni 64 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{56}{64}+\frac{49}{64}$$

-\frac{56}{64} va \frac{49}{64} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-56+49}{64}$$

-7 olish uchun -56 va 49'ni qo'shing.

$$-\frac{7}{64}$$

Omil

$$-\frac{7}{64} = -0,109375$$
