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