Yechim qadamlari

2 daraja ko‘rsatkichini -5 ga hisoblang va 25 ni qiymatni oling.

$$\frac{25-3^{2}+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

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

$$\frac{25-9+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

16 olish uchun 25 dan 9 ni ayirish.

$$\frac{16+\left(\frac{2}{3}\right)^{0}}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

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

$$\frac{16+1}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

17 olish uchun 16 va 1'ni qo'shing.

$$\frac{17}{3^{-2}+\frac{1}{5}+\frac{1}{2}}$$

-2 daraja ko‘rsatkichini 3 ga hisoblang va \frac{1}{9} ni qiymatni oling.

$$\frac{17}{\frac{1}{9}+\frac{1}{5}+\frac{1}{2}}$$

\frac{14}{45} olish uchun \frac{1}{9} va \frac{1}{5}'ni qo'shing.

$$\frac{17}{\frac{14}{45}+\frac{1}{2}}$$

\frac{73}{90} olish uchun \frac{14}{45} va \frac{1}{2}'ni qo'shing.

$$\frac{17}{\frac{73}{90}}$$

17 ni \frac{73}{90} ga bo'lish 17 ga k'paytirish \frac{73}{90} ga qaytarish.

$$17\times \frac{90}{73}$$

\frac{1530}{73} hosil qilish uchun 17 va \frac{90}{73} ni ko'paytirish.

$$\frac{1530}{73}$$

Omil

$$\frac{2 \cdot 3 ^ {2} \cdot 5 \cdot 17}{73} = 20\frac{70}{73} = 20,958904109589042$$
