f(x)=1/2(3)^xtext{when}x=5 eching

$$f ( x ) = \frac { 1 } { 2 } ( 3 ) ^ { x } \text { when } x = 5$$

f, x uchun yechish

$$x=5$$

$$f = \frac{243}{10} = 24\frac{3}{10} = 24,3$$

Yechim qadamlari

Birinchi tenglamani yeching. Tenglamaga o‘zgaruvchining ma’lum qiymatlarini joylang.

$$f\times 5=\frac{1}{2}\times 3^{5}$$

5 daraja ko‘rsatkichini 3 ga hisoblang va 243 ni qiymatni oling.

$$f\times 5=\frac{1}{2}\times 243$$

\frac{243}{2} hosil qilish uchun \frac{1}{2} va 243 ni ko'paytirish.

$$f\times 5=\frac{243}{2}$$

Ikki tarafini 5 ga bo‘ling.

$$f=\frac{\frac{243}{2}}{5}$$

\frac{\frac{243}{2}}{5} ni yagona kasrga aylantiring.

$$f=\frac{243}{2\times 5}$$

10 hosil qilish uchun 2 va 5 ni ko'paytirish.

$$f=\frac{243}{10}$$

Tizim hal qilindi.

$$f=\frac{243}{10} x=5$$
