Steps to solve an indefinite integral?

Explain how to solve the following indefinite integral:

x^3(10-x^4)^7 dx

Steps and explanations would be appreciated.

Also, is an indefinite integral an antiderivate... aka are they the same thing?

    u = 10 - x^4

    du = -4x^3 dx so x^3 dx = (-1/4) du

    Substitute and integrate...easy.

    yes they are the same thing an integral is an antiderivative

    use a u-substitution

    u = 10 - x^4

    du = -4x^3 dx so x^3 dx = (-1/4) du

    now you have the integral of xdx which becomes 1/2 u^2 +c and plug in the u(10-x^4)

    it fairly is a u-substitution issue, with x^4+2 being the u. This leaves 4x^3 as your du, and because x^3 is already interior the equation i might in basic terms pull out the 4 leaving a million/4 cases the imperative of cos(u) du. If i'm no longer incorrect, the respond might desire to be a million/4*sin(x^4+2).
