    Use power rule for integration.

    The 2 stays in the denominator.

    [tex]{{1}\over{2x^{7}}} = {{x^{-7}\over{2}}}[/tex]

    1/(2x^7) = 1/2 x^-7, not 2x^-7

    Alternatively, you may pull out any constant from the integral
    such that: [tex] \int \frac {dx}{2x^7} = \frac {1}{2} \int \frac {1}{x^7} dx = \frac {1}{2} \int x^{-7} dx [/tex]
    it makes the integration a bit easier.
