(34*10^-4)(23*10^-5) eching

$$( 34 \times 10 ^ { - 4 } ) ( 23 \times 10 ^ { - 5 } )$$

Baholash

$$\frac{391}{500000000}=0,000000782$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -4 va -5 ni qo‘shib, -9 ni oling.

$$34\times 10^{-9}\times 23$$

-9 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{1000000000} ni qiymatni oling.

$$34\times \frac{1}{1000000000}\times 23$$

\frac{17}{500000000} hosil qilish uchun 34 va \frac{1}{1000000000} ni ko'paytirish.

$$\frac{17}{500000000}\times 23$$

\frac{391}{500000000} hosil qilish uchun \frac{17}{500000000} va 23 ni ko'paytirish.

$$\frac{391}{500000000}$$

Omil

$$\frac{17 \cdot 23}{2 ^ {8} \cdot 5 ^ {9}} = 7,82 \times 10^{-7}$$
