Baholash

$$\frac{4219}{147}\approx 28,700680272$$

Yechim qadamlari

Surat va maxrajdagi ikkala 3 ni qisqartiring.

$$\frac{10^{-2}}{588\times 10^{-5}}+27$$

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

$$\frac{10^{3}}{588}+27$$

3 daraja ko‘rsatkichini 10 ga hisoblang va 1000 ni qiymatni oling.

$$\frac{1000}{588}+27$$

\frac{1000}{588} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{250}{147}+27$$

\frac{4219}{147} olish uchun \frac{250}{147} va 27'ni qo'shing.

$$\frac{4219}{147}$$

Omil

$$\frac{4219}{3 \cdot 7 ^ {2}} = 28\frac{103}{147} = 28,700680272108844$$
