5*10^-4*10^-2/9*10^9=x eching

$$\frac{ 5 \times { 10 }^{ -4 } \times { 10 }^{ -2 } }{ 9 \times { 10 }^{ 9 } } =x$$

x uchun yechish

$$x=\frac{1}{1800000000000000}\approx 5,555555556 \cdot 10^{-16}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ayni asosning daraja ko‘rsatkichlarini ko‘paytirish uchun ularning darajalarini qo‘shing. -4 va -2 ni qo‘shib, -6 ni oling.

$$\frac{5\times 10^{-6}}{9\times 10^{9}}=x$$

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

$$\frac{5}{9\times 10^{15}}=x$$

15 daraja ko‘rsatkichini 10 ga hisoblang va 1000000000000000 ni qiymatni oling.

$$\frac{5}{9\times 1000000000000000}=x$$

9000000000000000 hosil qilish uchun 9 va 1000000000000000 ni ko'paytirish.

$$\frac{5}{9000000000000000}=x$$

\frac{5}{9000000000000000} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{1800000000000000}=x$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$x=\frac{1}{1800000000000000}$$
