Solving a 'Stanford' University entrance exam | x=?

[@michaeldoerr5810]

This is surprisingly easy to show work on. And the answers are 1 and 4. Someone made a much more rigorous comment and shall compare that thought to your presentation so that I can sharpen my understanding and my practice!!!

you added ln for no reason, after x = x^square root of x/2 then 1 = square root of x/2 then x = 4
