    Simplification

    This is the original formula:
    p(\frac{p}{3w_1})^\frac{1}{2}x^\frac{1}{2}_2-w_1(\frac{p}{3w_1})^\frac{3}{2}x^\frac{1}{2}_2-w_2x_2


    This is how far I've gotten:
    \frac{2p}{3}(\frac{p}{3w_1})^\frac{1}{2}x^\frac{1}  {2}_{2}-w_2x_2


    And this is the final answer I need to get to:
    (\frac{4p^3}{27w_1})^\frac{1}{2}x^\frac{1}{2}_2-w_2x_2


    Any help would be greatly appreciated, thank you!

    All you need to do is get the outer 2p/3 rewritten as

    \sqrt{(4p^2/9)}

    Then it would have the same power as the other item raised to the 1/2 power so they could combine.
