Find the following limit. 5 In(x) lim x-1 X-1 Solution Since lim 5 In(x) = 5 In(1) = x-1 the limit is an indeterminate form, so we can apply l'Hospital's Rule. 5 In(x) lim X→1 X-1 = lim X→ 1 = lim = x → 1 = lim X→ 1 (5 -(5 In(x)) (x-1) 1 and lim (x - 1) = X→ 1

Find the following limit.
5 In(x)
lim
x 1 x 1
Solution
Since
lim 5 In(x) = 5 In(1) =
x → 1
5 In(x)
lim
x 1 x 1
the limit is an indeterminate form, so we can apply l'Hospital's Rule.
