Does integration feel like a second formula list, even though you know differentiation? Reverse the question: which function differentiates to the expression you have? That is an antiderivative. Since every constant differentiates to zero, all valid answers need +C. The power rule says: the integral of x to the n is x to the n plus one, divided by n plus one, plus C, for n not equal to minus one. Differentiate to check. Integration reverses differentiation.
