(+5+7-4)=+8ab^4 eching

$$( + 5 + 7 - 4 ) = + 8 a b ^ { 4 }$$

a uchun yechish

$$a=\frac{1}{b^{4}}$$

$$b\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

12 olish uchun 5 va 7'ni qo'shing.

$$12-4=8ab^{4}$$

8 olish uchun 12 dan 4 ni ayirish.

$$8=8ab^{4}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$8ab^{4}=8$$

Tenglama standart shaklda.

$$8b^{4}a=8$$

Ikki tarafini 8b^{4} ga bo‘ling.

$$\frac{8b^{4}a}{8b^{4}}=\frac{8}{8b^{4}}$$

8b^{4} ga bo'lish 8b^{4} ga ko'paytirishni bekor qiladi.

$$a=\frac{8}{8b^{4}}$$

8 ni 8b^{4} ga bo'lish.

$$a=\frac{1}{b^{4}}$$

b uchun yechish

$$b=\frac{1}{\sqrt[4]{a}}$$

$$b=-\frac{1}{\sqrt[4]{a}}\text{, }a>0$$
