firstly i just did it by hit and trial and x = 3√2(which is almost 2.13..) satisfied .Now for any value of x>3 you'll get a value of 'x' which will be lesser than 3√2 and thus the solution for 'x' that you obtain will be lesser that 3 ,which is not possible because x is greater than 3 already;so no solution for any x>3
Similarly u can prove that there's no solution for any x<2 also

pritishmast answer seems to be correct.
see
f(x) = 1 0<x<1
x 1<x<2
x2 2<x<3
thus the inequlity has a solution in 2<x<3 x = 3/√2
