To solve the equation \( \log_{3} 81 = x \), we can rewrite it in exponential form. This means that if \( \log_{3} 81 = x \), then \( 3^x = 81 \). Next, we need to express 81 as a power of 3. We know that \( 81 = 3^4 \). So, we can substitute this into our equation: \[ 3^x = 3^4 \] Since the bases are the same, we can set the exponents equal to each other: \[ x = 4 \] Thus, the solution to the equation is \( x = 4 \).
