Rewrite 3^x = 243 as a logarithmic equation. log3(243) = x logx(243) = 3 log3(x) = 243 log243(x) = 3

In general, the logarithmic function definition states that


y=log_b(x)\Leftrightarrow x=b^y

Therefore, in our case,


3^x=243\Leftrightarrow x=log_3(243)

Thus, the answer is log3(243)=x, the first option.
