    differentiate term by term using the general form if f\9) = ax^n then f'(x) = anx^(n-1)

    ax^n =a*nx^n-1

    Great, quick answers. Thanks. Could I use the definition and determine it by doing [2(x+h)^3+ 12(x+h)^2 ... etc.? And the power series method is just easier? Or is the definition not appropriate in this context?

    you could use the definition but the power method is valid here
