Yechim qadamlari

12 hosil qilish uchun 6 va 2 ni ko'paytirish.

$$\left(\frac{12+1}{2}\right)^{3}-2\times \frac{1^{2}}{4}-1$$

13 olish uchun 12 va 1'ni qo'shing.

$$\left(\frac{13}{2}\right)^{3}-2\times \frac{1^{2}}{4}-1$$

3 daraja ko‘rsatkichini \frac{13}{2} ga hisoblang va \frac{2197}{8} ni qiymatni oling.

$$\frac{2197}{8}-2\times \frac{1^{2}}{4}-1$$

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

$$\frac{2197}{8}-2\times \frac{1}{4}-1$$

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

$$\frac{2197}{8}-\frac{1}{2}-1$$

\frac{2193}{8} olish uchun \frac{2197}{8} dan \frac{1}{2} ni ayirish.

$$\frac{2193}{8}-1$$

\frac{2185}{8} olish uchun \frac{2193}{8} dan 1 ni ayirish.

$$\frac{2185}{8}$$

Omil

$$\frac{5 \cdot 19 \cdot 23}{2 ^ {3}} = 273\frac{1}{8} = 273,125$$
