Baholash

$$-\frac{xy^{2}}{3}$$

Yechim qadamlari

\frac{-3}{xy^{2}}ni darajaga oshirish uchun, surat va maxrajni darajaga oshirib, keyin bo‘ling.

$$\frac{\left(-3\right)^{-1}}{\left(xy^{2}\right)^{-1}}$$

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

$$\frac{-\frac{1}{3}}{\left(xy^{2}\right)^{-1}}$$

\left(xy^{2}\right)^{-1} ni kengaytirish.

$$\frac{-\frac{1}{3}}{x^{-1}\left(y^{2}\right)^{-1}}$$

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring. 2 va -1 ni ko‘paytirib, -2 ni oling.

$$\frac{-\frac{1}{3}}{x^{-1}y^{-2}}$$

\frac{-\frac{1}{3}}{x^{-1}y^{-2}} ni yagona kasrga aylantiring.

$$\frac{-1}{3x^{-1}y^{-2}}$$

x ga nisbatan hosilani topish

$$-\frac{y^{2}}{3}$$
