ln(x) is the natural logarithm of x, or the log of x base e. This is equivalent to loge(x) but ln(x) is normally preferred, in fact, for this question it is required.
log{base1}({arg1}) can be written in terms of natural logarithms as
Note: The natural log is denoted by ln, that is, an L (in lower case) followed by an n, the first letter is not a capital i. To enter your answer ensure you use the correct letters and use brackets.
