Thread: Solve 1

How would I solve these problems using a short cut formula, simplify results, collecting like terms if possible. I am totally lost with derivative, quotient and product rule.

f(x) =-8

g(x)=4x^-5+20x^-1

k(x)=15x 2/3

r(x)=16x^7-8x^5+4x^3-2x+1

f(x) = (√x+1)(Vx-1)

Ok. Some basic rules. The derivative of a constant is zero. That could be 1,2,3, pi, e, phi, etc. - the derivatives of all of these are zero.

If you have a polynomial in the form of , then So you can apply both of these rules to your f(x),g(x), and r(x).

On k(x), is that supposed to be , or ? I can't tell. And on the second f(x) term, is that supposed to be ?

Next time place the thread in the appropraite section.
