Need help on finding derivatives of logarithmic functions

[jzq]

These are the problems (Please, just point me in the right direction):

y=x^{2}\ln(6x)

f(x)=x\ln(12x)

Do you know the derivative of ln(x)?

Do you know the derivative of ln(x)?

The product rule -- d(uv)/dx = u'v + uv'
[edit: sorry had the answers, didnt know he didnt want to know them]

 

[whozum]

y = x^2ln(6x)

\frac{dy}{dx} = \frac{d(x^2ln(6x))}{dx}

which is of the form

\frac{d(u(x)v(x))}{dx} = u\frac{dv}{dx} + v\frac{du}{dx}

Use the chain rule when necessary (in the logarithm).
