@Nishant-Thakre but doubt is why lmvt is going wrong here.
@Nishant-Thakre can u explain after step 3
@Nishant-Thakre is there any other approach
@Nishant-Thakre bt how they how minimum goes to 6 if we can see 7.
@Nishant-Thakre didnt understand the last integral of LHS why it is not int(x-1) limt: from x-1 to x

@Nishant-Thakre u can do it by two methods:
@Nishant-Thakre i did x^n=t and normal piece-wise integration.
