Problem
Express the equation in logarithmic form: (a) $e^{x}=4$ is equivalent to $\ln A=B$. Then \[ A=4 \] and \[ B= \] (b) $e^{5}=x$ is equivalent to $\ln C=D$. Then \[ \text { C }= \] and \[ D= \] Question Help: $\square$ Video Submit Question
Solution
Step 1 ：\(e^{x}=4\) can be rewritten in logarithmic form as \(\ln 4 = x\). So, \(A=4\) and \(B=x\).
Step 2 ：\(e^{5}=x\) can be rewritten in logarithmic form as \(\ln x = 5\). So, \(C=x\) and \(D=5\).
