Answer:

Step-by-step explanation:

Definite integration:-

Here, at first we substitute n as 1/t,where t will tend to 0,as n tends to infinity.

After this substitution,we get a 0/0 form.

So,we apply L hospital rule,by differentiating both numerator and denominator to remove the indeterminate form.

In numerator,a definite integral is there.

So,we apply Newton Leibnitz rule for antiderivative of definite integral.

We assume y=t*2018^t

Applying log both sides,we get an indeterminate form again which is at power of e.

Again applying L hospital rule,we get y=1

But,there was a denominator of 2(y/2) if you observe carefully.

Hence required limit is 1/2.
