$open parentheses 2 space log invisible function application x minus 1 close parentheses fraction numerator 1 over denominator log presubscript space presuperscript x invisible function application 10 end fraction space equals log invisible function application 10 open parentheses 2 space log invisible function application x minus 1 close parentheses fraction numerator 1 over denominator log presubscript space presuperscript x invisible function application 10 end fraction space equals 1 open parentheses 2 space log invisible function application x minus 1 close parentheses log presubscript space presuperscript space invisible function application x space equals 1$

Misal:
log x= p
Maka:
open parentheses 2 p minus 1 close parentheses p equals 1 2 p squared minus p minus 1 equals 0 open parentheses 2 p plus 1 close parentheses open parentheses p minus 1 close parentheses equals 0

atau p= 1

dan

Jadi, hasil dari
