    Derivatives of Square Roots

    When taking the derivative of: 14/t + 12/t^4 + (square root of 2), how can I simplify the square root of 2 so I can complete the problem? Thanks!

    is this your expression ...

    \frac{14}{t} + \frac{12}{t^4 + \sqrt{2}}

    or

    \frac{14}{t} + \frac{12}{t^4} + \sqrt{2}

    or something else???

    \sqrt{2} is a constant.

    Sorry for the confusion, it's the 2nd (bottom) expression you listed.

    Re: Derivatives of Square Roots

    Why do you want to simplify \sqrt{2}? It's a constant number and the derivative of a constant number is ... ? For the other terms you have to use \frac{d}{dx}x^{n}=n\cdot x^{n-1} and offcourse the chain rule where necessary.
