ANSWER:
B
[tex]\log_3a=b[/tex]
EXPLANATION:
Given:
[tex]3^b=a[/tex]
To:
Rewrite the exponential function in logarithmic form
Note the below;
[tex]\begin{gathered} If\text{ }x^m=n, \\ \\ then; \\ \\ \log_xn=m \end{gathered}[/tex]
So we can go ahead and rewrite the given exponential function in logarithmic form as;
[tex]\begin{gathered} If\text{ }3^b=a, \\ \\ then; \\ \\ \log_3a=b \end{gathered}[/tex]
