Yechim qadamlari

Ayni asosning daraja ko‘rsatkichini bo‘lish uchun maxrajning darajasini surat darajasidan ayiring. 2 dan 1 ni ayirib, 1 ni oling.

$$2^{1}-8+\frac{8}{6}$$

1 daraja ko‘rsatkichini 2 ga hisoblang va 2 ni qiymatni oling.

$$2-8+\frac{8}{6}$$

-6 olish uchun 2 dan 8 ni ayirish.

$$-6+\frac{8}{6}$$

\frac{8}{6} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-6+\frac{4}{3}$$

-6 ni -\frac{18}{3} kasrga o‘giring.

$$-\frac{18}{3}+\frac{4}{3}$$

-\frac{18}{3} va \frac{4}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-18+4}{3}$$

-14 olish uchun -18 va 4'ni qo'shing.

$$-\frac{14}{3}$$

Omil

$$-\frac{14}{3} = -4\frac{2}{3} = -4,666666666666667$$
