    Did I do this question right?

    Hi everyone. I was working on a problem. Can someone please check whether I did this right?

    Let dy/dx = x^2y^2. Find d^2y/dx^2.

    This is what I did:

    2xy^2+2y*dy/dx*x^2
    2xy^2+2x^2y*dy/dx
    2xy^2+2x^2y(x^2y^2)
    2xy^2+2x^4y^3 This is my answer.

    Thanks a lot.
