\begin{tabular}{l} Write an equivalent exponential equation. \\ \( \qquad \log 10000=4 \) \\ \hline\end{tabular}

1. We start with the logarithmic equation: \[ \log 10000 = 4 \] 2. Recall the definition of the logarithm: \[ \log_a b = c \quad \Longleftrightarrow \quad a^c = b \] Here, the base \(a\) is assumed to be \(10\). 3. Using the definition, rewrite the equation in its exponential form: \[ 10^4 = 10000 \]
