Yechim qadamlari

2 daraja ko‘rsatkichini 5 ga hisoblang va 25 ni qiymatni oling.

$$4\times 25+6\times \frac{5}{4^{2}}$$

100 hosil qilish uchun 4 va 25 ni ko'paytirish.

$$100+6\times \frac{5}{4^{2}}$$

2 daraja ko‘rsatkichini 4 ga hisoblang va 16 ni qiymatni oling.

$$100+6\times \frac{5}{16}$$

6\times \frac{5}{16} ni yagona kasrga aylantiring.

$$100+\frac{6\times 5}{16}$$

30 hosil qilish uchun 6 va 5 ni ko'paytirish.

$$100+\frac{30}{16}$$

\frac{30}{16} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$100+\frac{15}{8}$$

100 ni \frac{800}{8} kasrga o‘giring.

$$\frac{800}{8}+\frac{15}{8}$$

\frac{800}{8} va \frac{15}{8} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{800+15}{8}$$

815 olish uchun 800 va 15'ni qo'shing.

$$\frac{815}{8}$$
