Finding Derivative of y=5^(3-3x)

[chantella28]

Hey guys,
I have a calculus problem that should be easy but I haven't taken calc in a few years so I can't remember where to begin. If somebody could give me some help with this, that would be great

find the following derivative: y=5^(3-3x)

You know the derivative of e^x and the chain rule (right?), so just use these along with the fact that:

5^{a}=e^{a \ln 5}
