Rewrite each equation as requested. (a) Rewrite as a logarithmic equation. \[ e^{6}=y \] (b) Rewrite as an exponential equation. \[ \ln x=4 \] (a) Џ $\square \log _{\square} \square \quad \square \ln \square$ (b)

Step 1 ：\(e^6 = y\) can be rewritten as \(\log_e(y) = 6\)

Step 2 ：Since the base e is the natural logarithm, we usually write it as ln, so the final answer is \(\ln(y) = 6\)

Step 3 ：\(\ln(x) = 4\) can be rewritten as \(e^4 = x\)

Step 4 ：So, the final answer is \(x = e^4\)

Step 5 ：The final answers are \(\boxed{\ln(y) = 6}\) and \(\boxed{x = e^4}\)
