Yechim qadamlari

-\sqrt{3}+5 ifodaning har bir elementini \sqrt{3}-2 ifodaning har bir elementiga ko‘paytirish orqali taqsimot qonuni xususiyatlarini qo‘llash mumkin.

$$\left(-\sqrt{3}\right)\sqrt{3}-2\left(-\sqrt{3}\right)+5\sqrt{3}-10$$

2 hosil qilish uchun -2 va -1 ni ko'paytirish.

$$\left(-\sqrt{3}\right)\sqrt{3}+2\sqrt{3}+5\sqrt{3}-10$$

7\sqrt{3} ni olish uchun 2\sqrt{3} va 5\sqrt{3} ni birlashtirish.

$$\left(-\sqrt{3}\right)\sqrt{3}+7\sqrt{3}-10$$

3 hosil qilish uchun \sqrt{3} va \sqrt{3} ni ko'paytirish.

$$-3+7\sqrt{3}-10$$

-13 olish uchun -3 dan 10 ni ayirish.

$$-13+7\sqrt{3}$$
