[0-1/2(1)^2]+[1/22^2-0]= eching

$$[ 0 - \frac { 1 } { 2 } ( 1 ) ^ { 2 } ] + [ \frac { 1 } { 2 } 2 ^ { 2 } - 0 ] =$$

Baholash

$$\frac{3}{2}=1,5$$

Yechim qadamlari

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

$$0-\frac{1}{2}\times 1+\frac{1}{2}\times 2^{2}-0$$

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

$$0-\frac{1}{2}+\frac{1}{2}\times 2^{2}-0$$

-\frac{1}{2} olish uchun 0 dan \frac{1}{2} ni ayirish.

$$-\frac{1}{2}+\frac{1}{2}\times 2^{2}-0$$

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$-\frac{1}{2}+\frac{1}{2}\times 4-0$$

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

$$-\frac{1}{2}+\frac{4}{2}-0$$

2 ni olish uchun 4 ni 2 ga bo‘ling.

$$-\frac{1}{2}+2-0$$

2 olish uchun 2 dan 0 ni ayirish.

$$-\frac{1}{2}+2$$

2 ni \frac{4}{2} kasrga o‘giring.

$$-\frac{1}{2}+\frac{4}{2}$$

-\frac{1}{2} va \frac{4}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-1+4}{2}$$

3 olish uchun -1 va 4'ni qo'shing.

$$\frac{3}{2}$$

Omil

$$\frac{3}{2} = 1\frac{1}{2} = 1,5$$
