2-(-7/4)^2+(-5/8)=-16/27 eching

$$2 - ( - \frac { 7 } { 4 } ) ^ { 2 } + ( - \frac { 5 } { 8 } ) = - \frac { 16 } { 27 }$$

Tasdiqlamoq

Yechim qadamlari

2 daraja ko‘rsatkichini -\frac{7}{4} ga hisoblang va \frac{49}{16} ni qiymatni oling.

$$2-\frac{49}{16}-\frac{5}{8}=-\frac{16}{27}$$

2 ni \frac{32}{16} kasrga o‘giring.

$$\frac{32}{16}-\frac{49}{16}-\frac{5}{8}=-\frac{16}{27}$$

\frac{32}{16} va \frac{49}{16} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{32-49}{16}-\frac{5}{8}=-\frac{16}{27}$$

-17 olish uchun 32 dan 49 ni ayirish.

$$-\frac{17}{16}-\frac{5}{8}=-\frac{16}{27}$$

16 va 8 ning eng kichik umumiy karralisi 16 ga teng. -\frac{17}{16} va \frac{5}{8} ni 16 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{17}{16}-\frac{10}{16}=-\frac{16}{27}$$

-\frac{17}{16} va \frac{10}{16} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-17-10}{16}=-\frac{16}{27}$$

-27 olish uchun -17 dan 10 ni ayirish.

$$-\frac{27}{16}=-\frac{16}{27}$$

16 va 27 ning eng kichik umumiy karralisi 432 ga teng. -\frac{27}{16} va -\frac{16}{27} ni 432 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{729}{432}=-\frac{256}{432}$$

-\frac{729}{432} va -\frac{256}{432} ni taqqoslang.
