    recall: \frac d{dx}a^x = a^x \ln a for a \in \mathbb{R}, a>0

    you will also need the product rule here, since you have a product of functions

    \frac d{dx}f(x)g(x) = f'(x)g(x) + f(x)g'(x)

    We don't need the product rule here, since 3^x\cdot5^x=(15)^x.

    Thanks again Jhevon for all the help you've given me over the last couple of weeks. I had my exam today and I'm pretty sure I got a 100 on it.
