In this question, we need to evaluate the following limit.
00:03
So let us see how we are going to do this.
00:05
First of all, we have been given that limit as extending to four f of x, it is already given as three.
00:14
Okay, so first part is to evaluate limit extending to four f of x whole cube.
00:24
So this is same as limit extending to four of f of x and whole cube we can apply here.
00:34
So this will be what three cubedest, so which is equals to 27.
00:40
Now let us move to the next part.
00:42
In the next part, we have to evaluate limit as extending to four of f of x square minus x squared divided with f of x plus x.
00:58
Okay, so we can and use this identity, a square minus b square is a plus b and a minus b.
01:07
Okay.
01:08
So with this what we get, we get limit extending to four, f of x plus x and another bracket, we get f of x minus x divided with f of x plus x...
