(7*10^-6)(7*10^-6)=49*10^-13 eching

$$(7 \times { 10 }^{ -6 } )(7 \times { 10 }^{ -6 } )=49 \times { 10 }^{ -13 }$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -6 va -6 ni qo‘shib, -12 ni oling.

$$7\times 10^{-12}\times 7=49\times 10^{-13}$$

-12 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{1000000000000} ni qiymatni oling.

$$7\times \frac{1}{1000000000000}\times 7=49\times 10^{-13}$$

\frac{7}{1000000000000} hosil qilish uchun 7 va \frac{1}{1000000000000} ni ko'paytirish.

$$\frac{7}{1000000000000}\times 7=49\times 10^{-13}$$

\frac{49}{1000000000000} hosil qilish uchun \frac{7}{1000000000000} va 7 ni ko'paytirish.

$$\frac{49}{1000000000000}=49\times 10^{-13}$$

-13 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{10000000000000} ni qiymatni oling.

$$\frac{49}{1000000000000}=49\times \frac{1}{10000000000000}$$

\frac{49}{10000000000000} hosil qilish uchun 49 va \frac{1}{10000000000000} ni ko'paytirish.

$$\frac{49}{1000000000000}=\frac{49}{10000000000000}$$

1000000000000 va 10000000000000 ning eng kichik umumiy karralisi 10000000000000 ga teng. \frac{49}{1000000000000} va \frac{49}{10000000000000} ni 10000000000000 maxraj bilan kasrlarga aylantirib oling.

$$\frac{490}{10000000000000}=\frac{49}{10000000000000}$$

\frac{490}{10000000000000} va \frac{49}{10000000000000} ni taqqoslang.
