So we're starting with limit as X goes to positive infinity of natural log of X, divided by X. Now, if we just go in and try to do this limit well, on the numerator, we get infinity on the denominator. We get infinity, we have infinity over infinity. That's an indeterminant form. And we're good to go to use low petals rule. I'm going to write LH over this equal sign indicating that we are using Low Patel's role in the next step so that the root of the numerator natural Lagerback's is going to be one over X and the derivative of the denominator X is one. Okay, and this new limit that we have could be evaluated. We're done.
