    Is the "1" after the first parentheses meant to be an exponent? Is the "n" before the second parentheses meant to be a constant?

    What have you tried? How far have you gotten?

    One way to start might be to solve for "y=", giving you y = 30/x = 30x^(-1). Then use the Power Rule.

    Is the "a" just a constant? If so, take it out front, along with the 4, and integrate x = x^1, using the Power Rule.

    If you get stuck, please reply showing how far you have gotten. Thank you!
