-2^2b=3^-3 eching

$$- 2 ^ { 2 } b = 3 ^ { - 3 }$$

b uchun yechish

$$b=-\frac{1}{108}\approx -0,009259259$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$-4b=3^{-3}$$

-3 daraja ko‘rsatkichini 3 ga hisoblang va \frac{1}{27} ni qiymatni oling.

$$-4b=\frac{1}{27}$$

Ikki tarafini -4 ga bo‘ling.

$$b=\frac{\frac{1}{27}}{-4}$$

\frac{\frac{1}{27}}{-4} ni yagona kasrga aylantiring.

$$b=\frac{1}{27\left(-4\right)}$$

-108 hosil qilish uchun 27 va -4 ni ko'paytirish.

$$b=\frac{1}{-108}$$

\frac{1}{-108} kasri manfiy belgini olib tashlash bilan -\frac{1}{108} sifatida qayta yozilishi mumkin.

$$b=-\frac{1}{108}$$
