KCF, when doing a division fraction problem, you keep the first fraction, change the division into multiplication, and flip the other fraction. For example:
1/4 / 4/7
turns into
1/4 x 7/4
it makes it easier to solve

How to solve an equation for x with natural log of x

Soloha48 [4]

Question is not specific, so can only give a general answer.
As an example:
If the equation is of the form
log(x)=5
then raise each side to the power of e to give
e^(log(x))=e^5
Since e^(log(x))=x, we have
x=e^5.
