Find dy/dx through implicit differentiation, cos(xy^2) = y

2cos(xy) x -sin(xy) x d/dx(xy)

Why is it when I try to get a derivative using the power rule I get a different result if I use the Chain rule

For example: f(x)=5x^2 f(x)=10x (Power Rule f(x)=x^n, f(x)=nx^(n-1)) f(x)=5x^2 g(x)=z=5x f(g(x))=f(z)=z^2 f(g(x))=f(z)=2z g(x)=z=5 f(z)*z=(2z)(5) =2(5x)(5) f(x)=50x (Chain Rule f(g(x))=f(g(x))*(g(x))
