Yechim qadamlari

3 daraja ko‘rsatkichini 7 ga hisoblang va 343 ni qiymatni oling.

$$\frac{343}{120}\times \frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$\frac{343}{120}\times \frac{6+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$\frac{343}{120}\times \frac{7}{3}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{343}{120} ni \frac{7}{3} ga ko‘paytiring.

$$\frac{343\times 7}{120\times 3}$$

\frac{343\times 7}{120\times 3} kasridagi ko‘paytirishlarni bajaring.

$$\frac{2401}{360}$$

Omil

$$\frac{7 ^ {4}}{2 ^ {3} \cdot 3 ^ {2} \cdot 5} = 6\frac{241}{360} = 6,669444444444444$$
