Answer:
Option A
\(\log_3 81 =x\)
Step-by-step explanation:
Use logarithmic rules:
- \(\log_a b = \frac{\log a}{\log b}\)
Given the equation:
\(81 = 3^x\)
Taking both side logarithm function:
\(\log 81 = x\log 3\)
Divide both sides by log 3 we have;
\(\frac{\log 81}{\log 3} = x\)
Apply the logarithmic rules:
\(\log_3 81 =x\)
therefore, \(81 = 3^x\) as a logarithmic equation is \(\log_3 81 =x\)
