Yechim qadamlari

-\frac{5}{4} olish uchun -2 va \frac{3}{4}'ni qo'shing.

$$\frac{\frac{\frac{5}{4}-\left(-\frac{5}{4}\right)^{2}}{\left(\frac{5}{4}\right)^{2}}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

2 daraja ko‘rsatkichini -\frac{5}{4} ga hisoblang va \frac{25}{16} ni qiymatni oling.

$$\frac{\frac{\frac{5}{4}-\frac{25}{16}}{\left(\frac{5}{4}\right)^{2}}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

-\frac{5}{16} olish uchun \frac{5}{4} dan \frac{25}{16} ni ayirish.

$$\frac{\frac{-\frac{5}{16}}{\left(\frac{5}{4}\right)^{2}}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

2 daraja ko‘rsatkichini \frac{5}{4} ga hisoblang va \frac{25}{16} ni qiymatni oling.

$$\frac{\frac{-\frac{5}{16}}{\frac{25}{16}}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

-\frac{5}{16} ni \frac{25}{16} ga bo'lish -\frac{5}{16} ga k'paytirish \frac{25}{16} ga qaytarish.

$$\frac{-\frac{5}{16}\times \frac{16}{25}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

-\frac{1}{5} hosil qilish uchun -\frac{5}{16} va \frac{16}{25} ni ko'paytirish.

$$\frac{-\frac{1}{5}-\left(-2\right)^{3}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

3 daraja ko‘rsatkichini -2 ga hisoblang va -8 ni qiymatni oling.

$$\frac{-\frac{1}{5}-\left(-8\right)}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

-8 ning teskarisi 8 ga teng.

$$\frac{-\frac{1}{5}+8}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

\frac{39}{5} olish uchun -\frac{1}{5} va 8'ni qo'shing.

$$\frac{\frac{39}{5}}{\frac{43}{5}-\left(-\frac{4}{5}\right)^{2}\left(2-\frac{3}{4}\right)}$$

2 daraja ko‘rsatkichini -\frac{4}{5} ga hisoblang va \frac{16}{25} ni qiymatni oling.

$$\frac{\frac{39}{5}}{\frac{43}{5}-\frac{16}{25}\left(2-\frac{3}{4}\right)}$$

\frac{5}{4} olish uchun 2 dan \frac{3}{4} ni ayirish.

$$\frac{\frac{39}{5}}{\frac{43}{5}-\frac{16}{25}\times \frac{5}{4}}$$

\frac{4}{5} hosil qilish uchun \frac{16}{25} va \frac{5}{4} ni ko'paytirish.

$$\frac{\frac{39}{5}}{\frac{43}{5}-\frac{4}{5}}$$

\frac{39}{5} olish uchun \frac{43}{5} dan \frac{4}{5} ni ayirish.

$$\frac{\frac{39}{5}}{\frac{39}{5}}$$

1 ni olish uchun \frac{39}{5} ni \frac{39}{5} ga bo‘ling.
