Yechim qadamlari

\sqrt[4]{\frac{1}{81}} ni hisoblab, \frac{1}{3} natijasiga ega bo‘ling.

$$\frac{1}{3}+\left(\frac{2}{3}\right)^{-1}-0,002\times 10^{3}$$

-1 daraja ko‘rsatkichini \frac{2}{3} ga hisoblang va \frac{3}{2} ni qiymatni oling.

$$\frac{1}{3}+\frac{3}{2}-0,002\times 10^{3}$$

\frac{11}{6} olish uchun \frac{1}{3} va \frac{3}{2}'ni qo'shing.

$$\frac{11}{6}-0,002\times 10^{3}$$

3 daraja ko‘rsatkichini 10 ga hisoblang va 1000 ni qiymatni oling.

$$\frac{11}{6}-0,002\times 1000$$

2 hosil qilish uchun 0,002 va 1000 ni ko'paytirish.

$$\frac{11}{6}-2$$

-\frac{1}{6} olish uchun \frac{11}{6} dan 2 ni ayirish.

$$-\frac{1}{6}$$

Omil

$$-\frac{1}{6} = -0,16666666666666666$$
