3*1+2{left(-1/2right)}^2*(1*(-1/2)) eching

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

Baholash

$$\frac{11}{4}=2,75$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 2 va 1 ni qo‘shib, 3 ni oling.

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

3 hosil qilish uchun 3 va 1 ni ko'paytirish.

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

3 daraja ko‘rsatkichini -\frac{1}{2} ga hisoblang va -\frac{1}{8} ni qiymatni oling.

$$3+2\left(-\frac{1}{8}\right)\times 1$$

2\left(-\frac{1}{8}\right) ni yagona kasrga aylantiring.

$$3+\frac{2\left(-1\right)}{8}\times 1$$

-2 hosil qilish uchun 2 va -1 ni ko'paytirish.

$$3+\frac{-2}{8}\times 1$$

\frac{-2}{8} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$3-\frac{1}{4}$$

3 ni \frac{12}{4} kasrga o‘giring.

$$\frac{12}{4}-\frac{1}{4}$$

\frac{12}{4} va \frac{1}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{12-1}{4}$$

11 olish uchun 12 dan 1 ni ayirish.

$$\frac{11}{4}$$

Omil

$$\frac{11}{2 ^ {2}} = 2\frac{3}{4} = 2,75$$
