To differentiate the function ( y = x^2 \ln(2x) + x \ln(3x) + 4 \ln x ), apply the product rule and the chain rule:

( \frac{dy}{dx} = \frac{d}{dx}[x^2 \ln(2x)] + \frac{d}{dx}[x \ln(3x)] + \frac{d}{dx}[4 \ln x] )

Using the product rule and the chain rule, differentiate each term separately:

( \frac{dy}{dx} = (2x \ln(2x) + x^2 \cdot \frac{1}{x} \cdot 2) + (\ln(3x) + x \cdot \frac{1}{3x} \cdot 3) + \frac{4}{x} )

Simplify each term:

( \frac{dy}{dx} = 2x \ln(2x) + 2x + \ln(3x) + 1 + \frac{4}{x} )

This is the derivative of the given function.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
