Im stuck on this problem: Differentiate the following function. Heres what i did: used sum rule, found the derivatives of the above terms. for the 1st one i got square root of 7 the 2nd i got .75u^-.5 so sqrt[7]+.75u^-.5 thanks.

You need to use the chain rule since the function is a composite function. The derivative should be So the derivative of is just . You can simplify the second term to the cubed root of the square of .
