-[-(1)^2/2+3/4(1)^3+1] eching

$$- [ - \frac { ( 1 ) ^ { 2 } } { 2 } + \frac { 3 } { 4 } ( 1 ) ^ { 3 } + 1 ]$$

Baholash

$$-\frac{5}{4}=-1,25$$

Yechim qadamlari

2 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$-\left(-\frac{1}{2}+\frac{3}{4}\times 1^{3}+1\right)$$

3 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$-\left(-\frac{1}{2}+\frac{3}{4}\times 1+1\right)$$

\frac{3}{4} hosil qilish uchun \frac{3}{4} va 1 ni ko'paytirish.

$$-\left(-\frac{1}{2}+\frac{3}{4}+1\right)$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. -\frac{1}{2} va \frac{3}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$-\left(-\frac{2}{4}+\frac{3}{4}+1\right)$$

-\frac{2}{4} va \frac{3}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\left(\frac{-2+3}{4}+1\right)$$

1 olish uchun -2 va 3'ni qo'shing.

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

1 ni \frac{4}{4} kasrga o‘giring.

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

\frac{1}{4} va \frac{4}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{1+4}{4}$$

5 olish uchun 1 va 4'ni qo'shing.

$$-\frac{5}{4}$$

Omil

$$-\frac{5}{4} = -1\frac{1}{4} = -1,25$$
