Differentiate each term with respect to x.

How do you differentiate the general term ax^n, where a and n are numbers, with respect to x?

Times by the power and then take one away from the power.
For example 16x^2 would be 32x. You're timesing by the power (2) and then taking one away from the power (2-1).

Hope that makes it clearer as to how to do your question.

Is that 8/x ?

Use the rule for ax^n ... d/dx =

d/dx[axⁿ] = nax^n-1
