  The point where the two curves intersect represents the solution to the equation. From the graph, you can see that the intersection occurs at approximately x=2.414

Let x>1  2^(1/x) (x−1)^(−(1/x)) =(x−1)^(x−2)   2^(1/x) =(x−1)^(((x−1)^2 )/x)   ((ln 2)/x)=(((x−1)^2 ln (x−1))/x)  ((ln 2)/(ln (x−1)))=(x−1)^2   x>1 ⇒ let x=1+(√t)  ((2ln 2)/(ln t))=t  2n 2 =tln t  t=2  x=1+(√2)

x>0  (2/(x−1))=(x−1)^(x(x−2))   2=(x−1)^(x(x−2)+1)   2=(x−1)^((x−1)^2 )   2^2 =[(x−1)^2 ]^((x−1)^2 )   ⇒(x−1)^2 =2  ⇒x=1+(√2)
