If you don't know how to start then you must not have learned the Product Rule yet. So you're going to have to multiply it out using algebra. The first step is to use the distributive property to write f(x) = (x^5)(4x^4 + 4x - 3) + (5x)(4x^4 + 4x - 3). Can you finish the multiplications and then take the derivative of the resulting polynomial?
