Difficult Floor Function... Please help

    hi i'm new here. For a couple of days i am struggling to methodically solve an equation involving the integer part of a fraction but nothing yet. The equation is;

    I found that the apparent solution is 53 as x HAS to be integer. Yet, I cannot mathematically prove how to compute x to be equal to 53. Any opinion is welcome, thanks!

    There is no way to solve the equation analytically with x and ln(x) like that. Numerical approaches are the best option, for small integer x this just means trial and error.

    52 to 56 all work for x.
