@Ray Vickson: That's a good question... I had a brainfart lol.
@jbunniii: Yeah, y is dependent on x... I forgot to mention that this is part of an Imp. Diff. problem. Thanks!
Homework Statement
\frac{d}{dx}x^{2}y^{2} = ?
Homework Equations
Power rule: \frac{d}{dx}x^{n} = nx^{n-1}
Product rule: \frac{d}{dx}[f(x)g(x)] = f'(x)g(x) + g'(x)f(x)
