Limits as x approaches picture:
A limit as x approaches picture is solved for by looking at the largest term in numerator and denominator.

For example:
In the problem,
picture picture picture is the term of the highest power in the equation so all other terms will drop out as we get to ∞. This would reduce to picture picture.  The picture terms cancel and we are left with picture picture, which equals picture.

Now look at, picture picture
In the numerator picture is the highest power in the denominator x ² is the highest power. This would reduce to picture picture. The picture terms cancel and we are left with from the top and bottom and we are left with picture picture. As x gets to ∞ this would become picture which is ∞, so picture picture

If the inverse was the case and the larger term was in the denominator, then the limit would be 0.
