Tenglamani yechish uchun eksponent va logaritmlarning qoidalaridan foydalanish.
2^{x-5}=\frac{125}{3}
Ikki tarafini 12 ga bo‘ling.
\log(2^{x-5})=\log(\frac{125}{3})
Tenglamaning ikkala tarafiga tegishli logaritmni chiqarish.
\left(x-5\right)\log(2)=\log(\frac{125}{3})
Darajaga ko'tarigan logaritm raqami raqam logaritmining darajasidir.
x-5=\frac{\log(\frac{125}{3})}{\log(2)}
Ikki tarafini \log(2) ga bo‘ling.
x-5=\log_{2}\left(\frac{125}{3}\right)
Asosiy tenglamani almashtirish orqali \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
x=\frac{\ln(\frac{125}{3})}{\ln(2)}-\left(-5\right)
5 ni tenglamaning ikkala tarafiga qo'shish.
