ans:

use D.L. Hospital low :

limx--> a = log(x-a)/ log (ex-ea) undetermined form (- infinite/ - infinite)

D.L. Hospital low ( differentiate Nrand Dr)
limx--> a = (ex-ea)/( x-a) ex again at x=a 0/0 form

again D.L. Hospital low ( differentiate Nrand Dr)
limx--> a = ex/ {xex + ex- aex}
now put the limit x--> a
= 1
