Answer:

[tex]\log_3x=2[/tex]

Step-by-step explanation:

The given equation is

[tex]3^2=x[/tex]

We need to express this equation as a logarithmic equation.

Taking log base 3 on both sides.

[tex]\log_33^2=\log_3x[/tex]

Using the property of logarithm, we get

[tex]2=\log_3x[/tex]          [tex][\because \log_aa^b=b][/tex]

Interchange the sides.

[tex]\log_3x=2[/tex]

Hence, the required equation is [tex]\log_3x=2[/tex].
