Question

Which of the following equations is equivalent to the logarithmic equationbelow?x = In4

Answer 1

A natural logarithm expression ln(x) = y can be rewritten as

$\begin{gathered} \ln (x)=y \\ e^y=x \end{gathered}$

Hence, for an expression

$\ln (4)=x$

This can be rewritten as

$e^x=4$

The answer to this problem is option D, which corresponds to the equation written above.
