So if you want to look at it at a very high level, you're saying, okay, well, x to the fourth, but it's under, you're gonna take the square root of this entire expression, so you could really view this as a second degree term. So the highest degree is really second degree, so let's divide the numerator and the denominator by x squared. And if we do that, dividing, so this is going to be the same thing as, so this is going to be the limit, the limit as x approaches negative infinity of, so let me just do a little bit of an aside here. So if I have one over x squared, or let me write it, let me, one over x squared times the square root of four x to the fourth minus x, like we have in the numerator here. This is equal to, this is the same thing as one over the square root of x to the fourth times the square root of four x to the fourth minus x. And so this is equal to the square root of four x to the fourth minus x over x to the fourth, which is equal to the square root of, and all I did is I brought the radical in here. This is, you could view this as the square root of all this divided by the square root of this, which is equal to, just using our exponent rules, the square root of four x to the fourth minus x over x to the fourth.
