Given,
The expression is:
[tex]3^x=27[/tex]Required:
The logarithm equation of the given equation.
The exponential equation is converted to logarithm form.
[tex]\begin{gathered} a^m=b \\ log_ab=m \end{gathered}[/tex]Taking the expression as:
[tex]\begin{gathered} 3^x=27 \\ log_327=x \end{gathered}[/tex]Hence, the logarithm expression is log_3 (27) = x.
