Use Quotient rule with
EDIT
My approach is slightly different from topsquark. You will need to use the chain rule twice with mine but they will both work in exactly the same way
Fractions and Square Roots...
Differentiate and simplify.
G(x) = square root of (3x+1/2x-1)
First, do I deal with this as a whole or break it down as two seperate functions: (3x+1) and (2x-1^1/2)
Second, I am not sure if I have written it to the correct power: 3x+1/2x-1^-1/2
-1/2(3x+1/2x-1)^-3/2
