1000*10^-6-7*10^-4 eching

$$1000 \times { 10 }^{ -6 } -7 \times { 10 }^{ -4 }$$

Baholash

$$\frac{3}{10000}=0,0003$$

Yechim qadamlari

-6 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{1000000} ni qiymatni oling.

$$1000\times \frac{1}{1000000}-7\times 10^{-4}$$

\frac{1}{1000} hosil qilish uchun 1000 va \frac{1}{1000000} ni ko'paytirish.

$$\frac{1}{1000}-7\times 10^{-4}$$

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

$$\frac{1}{1000}-7\times \frac{1}{10000}$$

\frac{7}{10000} hosil qilish uchun 7 va \frac{1}{10000} ni ko'paytirish.

$$\frac{1}{1000}-\frac{7}{10000}$$

\frac{3}{10000} olish uchun \frac{1}{1000} dan \frac{7}{10000} ni ayirish.

$$\frac{3}{10000}$$

Omil

$$\frac{3}{2 ^ {4} \cdot 5 ^ {4}} = 0,0003$$
