Explanation / Answer

g(x) = x/lnx ; [2 , 8]

==> g '(x) = [ (1) lnx - x(1/x)] / (lnx)2

==> g '(x) = (lnx -1)/(lnx)2

critical points ==> g '(x) = 0

==> (lnx -1)/(lnx)2 = 0

==> lnx = 1

==> x = e

g(e) = e/lne = e = 2.72

g(2) = 2/ln2 = 2.8854

g(8) = 8/ln8 = 3.8472

Hence absolute minima 2.72 at x = 2.72

absolute maximum 3.85 at x = 8
