Derivative of square roots and composition functions

  1. Oct 5, 2008 #1
    how do i take the derivative of sqr(4 + sqr(3x))?
    My teacher wants me to do it as a chain rule composition function so i separated it into

    F(x)= (4+x)^1/2 and G(x)= (3x)^1/2

    but i dont know where to go from here because i dont know how to take the derivative of f(x)

    on F(x) you must use the power rule then go inside your function and take the derivative
