Tenglamani yechish uchun eksponent va logaritmlarning qoidalaridan foydalanish.
10^{x}=10000
Ikkala tarafini 8 ga ko‘paytiring.
\log(10^{x})=\log(10000)
Tenglamaning ikkala tarafiga tegishli logaritmni chiqarish.
x\log(10)=\log(10000)
Darajaga ko'tarigan logaritm raqami raqam logaritmining darajasidir.
