The initial questions are meant as hints towards the final answer and also allow you the opportunity to get partial credit. Consider the indefinite integral ∫x3(5+10x1)10dx Then the most appropriate substitution to simplify this integral is u= Then dx=f(x)du where f(x)= After making the substitution we obtain the integral ∫g(u)du where g(u)= This last integral is: =+C (Leave out constant of integration from your answer.) After substituting back for u we obtain the following final form of the answer: =41000510​x4+C (Leave out constant of integration from your answer.)
