Natural logarithm ($ln(n)$, $lo{g}_e(n)$)

The natural logarithm is a logarithm that uses the mathematical constant \( e \) (approximately equal to 2.71828) as its base. It is denoted as \( \ln(x) \), where \( x \) is a positive real number. The natural logarithm answers the question: "To what power must \( e \) be raised to obtain \( x \)?
