Step 1 :Express the given exponential equations in logarithmic form.
Step 2 :For the first equation, \(e^{x}=5\), express it in logarithmic form as \(\log_{e}5=x\).
Step 3 :Since the base \(e\) is the natural logarithm, simplify it further as \(\ln5=x\).
Step 4 :For the second equation, \(e^{4}=x\), express it in logarithmic form as \(\log_{e}x=4\).
Step 5 :Again, since the base \(e\) is the natural logarithm, simplify it further as \(\ln x=4\).
Step 6 :Final Answer: (a) The logarithmic form of the equation \(e^{x}=5\) is \(\boxed{\ln5=x}\). (b) The logarithmic form of the equation \(e^{4}=x\) is \(\boxed{\ln x=4}\).
