Yechim qadamlari

81 va 9 ichida eng katta umumiy 9 faktorini bekor qiling.

$$-9\sqrt{3}+\frac{2}{3}\sqrt{3}\left(-9\right)+3\sqrt{3}$$

\frac{2}{3}\left(-9\right) ni yagona kasrga aylantiring.

$$-9\sqrt{3}+\frac{2\left(-9\right)}{3}\sqrt{3}+3\sqrt{3}$$

-18 hosil qilish uchun 2 va -9 ni ko'paytirish.

$$-9\sqrt{3}+\frac{-18}{3}\sqrt{3}+3\sqrt{3}$$

-6 ni olish uchun -18 ni 3 ga bo‘ling.

$$-9\sqrt{3}-6\sqrt{3}+3\sqrt{3}$$

-15\sqrt{3} ni olish uchun -9\sqrt{3} va -6\sqrt{3} ni birlashtirish.

$$-15\sqrt{3}+3\sqrt{3}$$

-12\sqrt{3} ni olish uchun -15\sqrt{3} va 3\sqrt{3} ni birlashtirish.

$$-12\sqrt{3}$$
