20^{8v}=355
Tenglamani yechish uchun eksponent va logaritmlarning qoidalaridan foydalanish.
\log(20^{8v})=\log(355)
Tenglamaning ikkala tarafiga tegishli logaritmni chiqarish.
8v\log(20)=\log(355)
Darajaga ko'tarigan logaritm raqami raqam logaritmining darajasidir.
8v=\frac{\log(355)}{\log(20)}
Ikki tarafini \log(20) ga bo‘ling.
8v=\log_{20}\left(355\right)
Asosiy tenglamani almashtirish orqali \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
v=\frac{\log_{20}\left(355\right)}{8}
Ikki tarafini 8 ga bo‘ling.
