Yechim qadamlari

\frac{-3}{4} kasri manfiy belgini olib tashlash bilan -\frac{3}{4} sifatida qayta yozilishi mumkin.

$$\left(-\frac{3}{4}\right)^{4}\times \left(\frac{16}{7}\right)^{2}$$

4 daraja ko‘rsatkichini -\frac{3}{4} ga hisoblang va \frac{81}{256} ni qiymatni oling.

$$\frac{81}{256}\times \left(\frac{16}{7}\right)^{2}$$

2 daraja ko‘rsatkichini \frac{16}{7} ga hisoblang va \frac{256}{49} ni qiymatni oling.

$$\frac{81}{256}\times \frac{256}{49}$$

\frac{81}{49} hosil qilish uchun \frac{81}{256} va \frac{256}{49} ni ko'paytirish.

$$\frac{81}{49}$$

Omil

$$\frac{3 ^ {4}}{7 ^ {2}} = 1\frac{32}{49} = 1,653061224489796$$
