6-158.

As you work through this set of problems, look for patterns.

Chain Rule.

This one is tricky. Concentrate on the 3x² part of the integrand. What will happen when you anti-differentiate that part?

Refer to part (a) (the question, not the hint).

Before you differentiate, rewrite the expression as with a fractional exponent.

A clue is directly above (in part (c)).

And don't forget the +*C*.
