The logarithmic equation of the given exponential function is , [tex]\rm log_864=x[/tex].
The logarithmic function is given as the inverse of the exponential function.
It is given as:
[tex]\rm Exponential\;function\rightarrow y=a^x\\Logarithmic\;function\rightarrow log_xy=a[/tex]
The logarithmic function of the given exponential equation is given as:
[tex]\rm y=a^x\\\\8^x=64\\log\;on \;both\;sides\\log_864=x[/tex]
Thus, the logarithmic equation is, [tex]\rm log_864=x[/tex]. Hence, option A is correct.
