SUMMARY

The discussion focuses on solving equations that involve floor functions and logarithms, specifically the equation where the integer part of a fraction is considered. The apparent solution identified is x = 53, which is confirmed to be an integer. However, the participants agree that analytical solutions are not feasible, and numerical methods, particularly trial and error for small integer values, are the most effective approach. Values from 52 to 56 are also noted as valid solutions for x.

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.
