Yechim qadamlari

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

$$8,4+3\left(-4\times 0,25+3^{2}\right)+4,1+2$$

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

$$8,4+3\left(-1+3^{2}\right)+4,1+2$$

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

$$8,4+3\left(-1+9\right)+4,1+2$$

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

$$8,4+3\times 8+4,1+2$$

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

$$8,4+24+4,1+2$$

32,4 olish uchun 8,4 va 24'ni qo'shing.

$$32,4+4,1+2$$

36,5 olish uchun 32,4 va 4,1'ni qo'shing.

$$36,5+2$$
