Homework Help: Indefinite integration

  1. Jun 19, 2012 #1
    1. The problem statement, all variables and given/known data
    1 / (3√x2 )


    2. Relevant equations



    3. The attempt at a solution
    the overall power of x in denom becomes ( 1/2 * 2 * 1/3 = 1/3)
    taking in num , it becomes (-1/3 + 1 = 2/3) so answer should be x2/3 / (2/3)
    which is wrong , plz help

    [itex]\displaystyle \frac{1}{\sqrt[3]{x^2}\,}=\frac{1}{x^{2/3}}=x^{-2/3}[/itex]

    [itex]\displaystyle -\frac{2}{3}+1=\frac{1}{3}[/itex]
