integrate 2^(3x). 3^(2x) . 5^(x) dx

  • maths -

    ∫a^(cx) dx = 1/(c lna) a^x

    now just use the product rule

  • maths -

    oops. how could I have mixed up derivatives with integrals? There is no product rule.

    However, we do have 8^x * 9^x * 5^x = 360^x

    which should be easy to do, no?
