So this whole thing has simplified, this whole thing is equal to five times this business. So I could actually just write it as, it's equal to five over, five over the natural log of 10, natural log of 10 times two. I could have written it as two natural log of 10s. The key here for this type of exercise, you might be like, oh let me see if I can evaluate this limit, but you're like, well, this looks a lot like the derivative of a logarithmic function, especially the derivative when x is equal to two, if we could just factor these fives out. So you factor out the five, you say, hey, this is the derivative of log of x when x is equal to two. And so we know how to take the derivative of log of x. If you don't know, we have videos where we prove this, where we take the derivatives of logarithms with bases other than e, and you just use that to actually, and you find the derivative, then you evaluate it at two, and then you're done.
