Yechim qadamlari

0,84 hosil qilish uchun 8,4 va 0,1 ni ko'paytirish.

$$0,84+3\left(-4\times 0,25+3^{2}\right)+\frac{4,1}{2}$$

-1 hosil qilish uchun -4 va 0,25 ni ko'paytirish.

$$0,84+3\left(-1+3^{2}\right)+\frac{4,1}{2}$$

2 daraja ko‘rsatkichini 3 ga hisoblang va 9 ni qiymatni oling.

$$0,84+3\left(-1+9\right)+\frac{4,1}{2}$$

8 olish uchun -1 va 9'ni qo'shing.

$$0,84+3\times 8+\frac{4,1}{2}$$

24 hosil qilish uchun 3 va 8 ni ko'paytirish.

$$0,84+24+\frac{4,1}{2}$$

24,84 olish uchun 0,84 va 24'ni qo'shing.

$$24,84+\frac{4,1}{2}$$

\frac{4,1}{2} kasrini uning surat va maxrajini 10 ga ko‘paytirish bilan kengaytiring.

$$24,84+\frac{41}{20}$$

24,84 o‘nlik raqamni uning \frac{2484}{100} kasrga o‘giring. \frac{2484}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{621}{25}+\frac{41}{20}$$

25 va 20 ning eng kichik umumiy karralisi 100 ga teng. \frac{621}{25} va \frac{41}{20} ni 100 maxraj bilan kasrlarga aylantirib oling.

$$\frac{2484}{100}+\frac{205}{100}$$

\frac{2484}{100} va \frac{205}{100} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{2484+205}{100}$$

2689 olish uchun 2484 va 205'ni qo'shing.

$$\frac{2689}{100}$$

Omil

$$\frac{2689}{2 ^ {2} \cdot 5 ^ {2}} = 26\frac{89}{100} = 26,89$$
