SOLUTION
Solve the expression below:
[tex]log_5(x)=2.1[/tex][tex]\begin{gathered} log_5(x)=2.1 \\ add\text{ log to base 5 to the other side} \\ log_5(x)=log_55^{2.1} \end{gathered}[/tex]
Cancel log to base 5 on both side of the expression
[tex]\begin{gathered} log_5x=log_55^{2.1} \\ x=5^{2.1} \\ x=29.36547 \\ x=29.37\text{ \lparen2d.p\rparen} \end{gathered}[/tex]
Hence the correct answer = Option A
