Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 5 va 2 ni qo‘shib, 7 ni oling.

$$\frac{1}{2}\times 5\times 10^{5}\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

\frac{5}{2} hosil qilish uchun \frac{1}{2} va 5 ni ko'paytirish.

$$\frac{5}{2}\times 10^{5}\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

5 daraja ko‘rsatkichini 10 ga hisoblang va 100000 ni qiymatni oling.

$$\frac{5}{2}\times 100000\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

\frac{5}{2}\times 100000 ni yagona kasrga aylantiring.

$$\frac{5\times 100000}{2}\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

500000 hosil qilish uchun 5 va 100000 ni ko'paytirish.

$$\frac{500000}{2}\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

250000 ni olish uchun 500000 ni 2 ga bo‘ling.

$$250000\times 30^{2}-\frac{1}{2}\times 5\times 10^{7}$$

2 daraja ko‘rsatkichini 30 ga hisoblang va 900 ni qiymatni oling.

$$250000\times 900-\frac{1}{2}\times 5\times 10^{7}$$

225000000 hosil qilish uchun 250000 va 900 ni ko'paytirish.

$$225000000-\frac{1}{2}\times 5\times 10^{7}$$

\frac{5}{2} hosil qilish uchun \frac{1}{2} va 5 ni ko'paytirish.

$$225000000-\frac{5}{2}\times 10^{7}$$

7 daraja ko‘rsatkichini 10 ga hisoblang va 10000000 ni qiymatni oling.

$$225000000-\frac{5}{2}\times 10000000$$

\frac{5}{2}\times 10000000 ni yagona kasrga aylantiring.

$$225000000-\frac{5\times 10000000}{2}$$

50000000 hosil qilish uchun 5 va 10000000 ni ko'paytirish.

$$225000000-\frac{50000000}{2}$$

25000000 ni olish uchun 50000000 ni 2 ga bo‘ling.

$$225000000-25000000$$

200000000 olish uchun 225000000 dan 25000000 ni ayirish.
