Can you use any method to solve or do you need to use the fundamental theorem?
Is the first one or ?

have you tried the quotient rule for derivatives?
Well first of all, since you're dividing by ALL of , you needed to write it as sqrt[x]/(2sqrt[x] + 3)... Now you should apply the Quotient Rule, namely if and , then .
yeah im just having trouble with the square roots though . like do i get rid of them ?
Remember that . Then you can apply the power rule for derivatives... BTW, since this is clearly a Calculus question, why have you posted in Pre-Calculus?
thanks for the help
taking the derivative of functions with in them are much easier if you remember that its derivative is . quotient rule ... multiply stuff in the numerator and combine like terms ... clean it up ...
