Simple Integral question! (Exponents)

  1. Nov 29, 2008 #1
    1. The problem statement, all variables and given/known data
    [tex]\int \frac{6^x+12^x}{2^x}dx[/tex]

    2. Relevant equations
    [tex]\int a^udu= \frac{a^u}{ln a} +C[/tex]

    3. The attempt at a solution
    I don't know where to begin, I tried using parts but gave up.

    Make your life simpler by getting rid of the denominator.

    6^x = (2 * 3)^x = 2^x * 3^x. You can apply the same idea to 12^x.
