663*10^-34/27*10^7*91*10^-31 eching

$$\frac { 663 \times 10 ^ { - 34 } } { 27 \times 10 ^ { 7 } \times 91 \times 10 ^ { - 31 } }$$

Baholash

$$\frac{17}{630000000000}\approx 2,698412698 \cdot 10^{-11}$$

Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 7 va -31 ni qo‘shib, -24 ni oling.

$$\frac{663\times 10^{-34}}{27\times 10^{-24}\times 91}$$

Surat va maxrajdagi ikkala 3\times 13 ni qisqartiring.

$$\frac{17\times 10^{-34}}{7\times 9\times 10^{-24}}$$

Ayni asosning daraja ko‘rsatkichini bo‘lish uchun suratning darajasini maxraj darajasiga bo‘ling.

$$\frac{17}{7\times 9\times 10^{10}}$$

63 hosil qilish uchun 7 va 9 ni ko'paytirish.

$$\frac{17}{63\times 10^{10}}$$

10 daraja ko‘rsatkichini 10 ga hisoblang va 10000000000 ni qiymatni oling.

$$\frac{17}{63\times 10000000000}$$

630000000000 hosil qilish uchun 63 va 10000000000 ni ko'paytirish.

$$\frac{17}{630000000000}$$

Omil

$$\frac{17}{2 ^ {10} \cdot 3 ^ {2} \cdot 5 ^ {10} \cdot 7} = 2,6984126984126986 \times 10^{-11}$$
