Yechim qadamlari

-\frac{7}{2} olish uchun -\frac{1}{2} dan 3 ni ayirish.

$$\left(-\frac{7}{2}\right)^{2}-\left(-\frac{1}{2}\left(5\left(-\frac{1}{2}\right)-6\right)\right)$$

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

$$\frac{49}{4}-\left(-\frac{1}{2}\left(5\left(-\frac{1}{2}\right)-6\right)\right)$$

-\frac{5}{2} hosil qilish uchun 5 va -\frac{1}{2} ni ko'paytirish.

$$\frac{49}{4}-\left(-\frac{1}{2}\left(-\frac{5}{2}-6\right)\right)$$

-\frac{17}{2} olish uchun -\frac{5}{2} dan 6 ni ayirish.

$$\frac{49}{4}-\left(-\frac{1}{2}\left(-\frac{17}{2}\right)\right)$$

\frac{17}{4} hosil qilish uchun -\frac{1}{2} va -\frac{17}{2} ni ko'paytirish.

$$\frac{49}{4}-\frac{17}{4}$$

8 olish uchun \frac{49}{4} dan \frac{17}{4} ni ayirish.
