Yechim qadamlari

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -6 va 23 ni qo‘shib, 17 ni oling.

$$\frac{10^{17}\times 16\times 10^{-19}}{4\times 7\times 10^{-3}}$$

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. 17 va -19 ni qo‘shib, -2 ni oling.

$$\frac{10^{-2}\times 16}{4\times 7\times 10^{-3}}$$

Surat va maxrajdagi ikkala 4 ni qisqartiring.

$$\frac{4\times 10^{-2}}{7\times 10^{-3}}$$

Ayni asosning daraja ko'rsatkichi bo'lish uchun maxrajning darajasini surat darajasidan bo'ling.

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

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

$$\frac{4\times 10}{7}$$

40 hosil qilish uchun 4 va 10 ni ko'paytirish.

$$\frac{40}{7}$$

Omil

$$\frac{2 ^ {3} \cdot 5}{7} = 5\frac{5}{7} = 5,714285714285714$$
