Step by step solution

01

Step 1. Given information.

Consider the given information,

limx1x1x-1

02

Step 2. Taking log on both sides.

Apply the logarithm property to simplify.

limx1+lnx1x-1=limx1+1(x1)lnxsince,log(a)b=blog(a)=limx1+lnx(x1)(00form)=limx1+1x(L'hospitalrule)=limx1+1x=1
03

Step 3. Calculating the value of the limit.

Find the limit from the above concepts,

limx1+x1(x1)=e1=e
