So I'm assuming you've had a go at it, and so there's a couple of interesting things here. The first thing, at least that my brain does, it says, well, I'm used to taking derivatives and antiderivatives of e to the x. Not some other base to the x. So we know that the derivative with respect to x of e to the x is e to the x, or we could say that the antiderivative of e to the x is equal to e to the x plus c. So since I'm dealing with something raised to a, this particular situation, something raised to a function of x, it seems like I might wanna put some, I might wanna change the base here. But how do I do that? Well, the way I would do that is re-express two in terms of e. So what would be two in terms of e? Well, two is equal to e, is equal to e raised to the power that you need to raise e to to get to two.
