Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 1 va -4 ni qo‘shib, -3 ni oling.

$$\frac{1000\times 10^{-3}\times 15}{1-1000\times 15\times 10^{-4}}$$

-3 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{1000} ni qiymatni oling.

$$\frac{1000\times \frac{1}{1000}\times 15}{1-1000\times 15\times 10^{-4}}$$

1 hosil qilish uchun 1000 va \frac{1}{1000} ni ko'paytirish.

$$\frac{15}{1-1000\times 15\times 10^{-4}}$$

15000 hosil qilish uchun 1000 va 15 ni ko'paytirish.

$$\frac{15}{1-15000\times 10^{-4}}$$

-4 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000} ni qiymatni oling.

$$\frac{15}{1-15000\times \frac{1}{10000}}$$

\frac{3}{2} hosil qilish uchun 15000 va \frac{1}{10000} ni ko'paytirish.

$$\frac{15}{1-\frac{3}{2}}$$

-\frac{1}{2} olish uchun 1 dan \frac{3}{2} ni ayirish.

$$\frac{15}{-\frac{1}{2}}$$

15 ni -\frac{1}{2} ga bo'lish 15 ga k'paytirish -\frac{1}{2} ga qaytarish.

$$15\left(-2\right)$$

-30 hosil qilish uchun 15 va -2 ni ko'paytirish.
