Question

Which exponential equation is equivalent to the logarithmic equation below?4 = ln xA.x = 10^4B.x = e^4C.x = 4eD.e = x4

Answer 1

`\begin{gathered} We\text{ are asked to convert lnx =4 into a logartithmic equation.} \\ We\text{ will take both sides and make them into a power of e} \\ e^(lnx)\text{ = e}^4 \\ We\text{ know that e}^(lnx)\text{ = x} \\ x\text{ = e}^4 \end{gathered}`

Correct option: B
