6*10^-7/8*10^-8 eching

$$\frac { 6 \times 10 ^ { - 7 } } { 8 \times 10 ^ { - 8 } }$$

Baholash

$$\frac{15}{2}=7,5$$

Yechim qadamlari

Surat va maxrajdagi ikkala 2 ni qisqartiring.

$$\frac{3\times 10^{-7}}{4\times 10^{-8}}$$

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

$$\frac{3\times 10^{1}}{4}$$

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

$$\frac{3\times 10}{4}$$

30 hosil qilish uchun 3 va 10 ni ko'paytirish.

$$\frac{30}{4}$$

\frac{30}{4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{15}{2}$$

Omil

$$\frac{3 \cdot 5}{2} = 7\frac{1}{2} = 7,5$$
