Yechim qadamlari

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

$$\left(\frac{1}{3}+4^{-1}\right)^{-1}$$

-1 daraja ko‘rsatkichini 4 ga hisoblang va \frac{1}{4} ni qiymatni oling.

$$\left(\frac{1}{3}+\frac{1}{4}\right)^{-1}$$

\frac{7}{12} olish uchun \frac{1}{3} va \frac{1}{4}'ni qo'shing.

$$\left(\frac{7}{12}\right)^{-1}$$

-1 daraja ko‘rsatkichini \frac{7}{12} ga hisoblang va \frac{12}{7} ni qiymatni oling.

$$\frac{12}{7}$$

Omil

$$\frac{2 ^ {2} \cdot 3}{7} = 1\frac{5}{7} = 1,7142857142857142$$
