(-1)*(-3/2)^2-3*(-3/2)+28 eching

$$( - 1 ) \times ( - \frac { 3 } { 2 } ) ^ { 2 } - 3 \times ( - \frac { 3 } { 2 } ) + 28$$

Baholash

$$\frac{121}{4}=30,25$$

Yechim qadamlari

2 daraja ko‘rsatkichini -\frac{3}{2} ga hisoblang va \frac{9}{4} ni qiymatni oling.

$$-\frac{9}{4}-3\left(-\frac{3}{2}\right)+28$$

3\left(-\frac{3}{2}\right) ni yagona kasrga aylantiring.

$$-\frac{9}{4}-\frac{3\left(-3\right)}{2}+28$$

-9 hosil qilish uchun 3 va -3 ni ko'paytirish.

$$-\frac{9}{4}-\frac{-9}{2}+28$$

\frac{-9}{2} kasri manfiy belgini olib tashlash bilan -\frac{9}{2} sifatida qayta yozilishi mumkin.

$$-\frac{9}{4}-\left(-\frac{9}{2}\right)+28$$

-\frac{9}{2} ning teskarisi \frac{9}{2} ga teng.

$$-\frac{9}{4}+\frac{9}{2}+28$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. -\frac{9}{4} va \frac{9}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{9}{4}+\frac{18}{4}+28$$

-\frac{9}{4} va \frac{18}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-9+18}{4}+28$$

9 olish uchun -9 va 18'ni qo'shing.

$$\frac{9}{4}+28$$

28 ni \frac{112}{4} kasrga o‘giring.

$$\frac{9}{4}+\frac{112}{4}$$

\frac{9}{4} va \frac{112}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{9+112}{4}$$

121 olish uchun 9 va 112'ni qo'shing.

$$\frac{121}{4}$$

Omil

$$\frac{11 ^ {2}}{2 ^ {2}} = 30\frac{1}{4} = 30,25$$
