Differentiate the following: sqrt[10/(4+x)]

  1. Nov 16, 2008 #1
    i need to differentiate the following:

    sqrt[10/(4+x)]

    so i re-wrote it as:

    [10(4+x)^-1]^1/2

    but am getting very confused when i try to differentiate it.

    any help would be great! cheers

    Re: differentiation

    Could you show your attempt at differentiating the expression?

    Step by step using the chain rule
    What is the derivative of u-1/2?

    What is the derivative of v-1?

    Re: differentiation

    well first i differentiated 10(4+x)^-1
    which is -10(4+x)^-2

    but i dont know how to include the sqrt....
