    You can't possibly have even set up the double integral properly - if you are integrating with respect to \displaystyle y first then your innermost bounds need a function of \displaystyle x, not \displaystyle y.

    Please post the entire question.

    You can't do the integration with respect to \displaystyle x first since there is not a closed form for the integral of \displaystyle \frac{e^{x^2}}{x^3}. Again, please post the entire original question.

    I thought you can change the limits of integration to
    0-4,0-x^2 dydx

    ummm no Prove it is correct. You have written

    \int_{0}^{4}\int_{\sqrt{y}}^{2}\frac{ye^{x^2}}{x^3  }dydx

    Do you See the problem with what you posted. You are integrating with respect to y first and have it as a function of y. That does not make sense. After integration you would still have y's in your integrand but no y differential.
