Does #a_n={(3/n)^(1/n)} #converge? If so what is the limit? Calculus Tests of Convergence / Divergence Infinite Sequences 1 Answer Jim H Mar 27, 2016 It converges to #1#. Explanation: #f(x) = (3/x)^(1/x) = e^(ln(3/x)/x)# #lim_(xrarroo)(ln(3/x)/x)# has initial form #(-oo)/oo# which is indeterminate, so use l'Hospital's rule. #lim_(xrarroo) (x/3(-3/x^2))/1 = lim_(xrarr0)-1/x = 0# Since the exponent goes to #0#, we have #lim_(xrarroo)(ln(3/x)/x) = e^0 = 1# Answer link Related questions What is the difference between an infinite sequence and an infinite series?
