e^x =logx

ex=logx

e^x =logx  e^e^x  =x  e^e^e^e^d^d^d      =x  e^x =x  x=logx  e^(−logx) =(1/(logx))  −logxe^(−logx) =−  −logx=W_0 (−1)  x=e^(−W_0 (−1))    (Complex solution x∈C)  Error!  e^x =logx  And e^x =x   (dosen′t satisfy any condition)

from graph it is clear that e^x  and lnx never cross  each other ...so no solution
