    \[\frac{ 2x+4 }{ \sqrt{2x+4} }\]

    take a look at this: http://en.wikipedia.org/wiki/Quotient_rule theres a simple formula for it do you know the chain rule?

    Hint: \[ \sqrt{2x+4} \cdot \sqrt{2x+4} = 2x+4\]So\[ \frac{ 2x+4 }{ \sqrt{2x+4} } = \sqrt{2x+4} \]

    mm i did the process step by step,, then i got = \[\frac{ 1 }{ \sqrt{2x+4} }\]
