10^{-x+1}=30
Tenglamani yechish uchun eksponent va logaritmlarning qoidalaridan foydalanish.
\log(10^{-x+1})=\log(30)
Tenglamaning ikkala tarafiga tegishli logaritmni chiqarish.
\left(-x+1\right)\log(10)=\log(30)
Darajaga ko'tarigan logaritm raqami raqam logaritmining darajasidir.
-x=\log(30)-1
Tenglamaning ikkala tarafidan 1 ni ayirish.
x=\frac{\log(30)-1}{-1}
Ikki tarafini -1 ga bo‘ling.
