Answer:

Option A

\log_3 81 =x

Step-by-step explanation:

Use logarithmic rules:

  • \log a^m = m\log a
  • \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
