wait 1 sec.
Ok this is reasonably difficult, you have to use the chain rule and the quotient rule.
Using the chain rule:
derivative = [ (1/2) * ( (2x + 3) / (7x+4) ) ^ (-1/2) ] * [d/dx (2x+3) / (7x+4) ]
So now you to use the quotient rule to find:
d/dx (2x+3) / (7x+4) = (14x+8 - 14x + 21) / (7x+4)^2
= 29 / (7x+4)^2
So the derivative is [1/2 * ((2x+3)/(7x+4))^(-1/2)]*[29 / (7x+4)^2]
By the way i got the thumbs down before I wrote all this up, so it doesn't mean it's wrong.

we're doing this in calculus right now..
i wont finish it but wouldnt it be:
1/2 ((quotient rule)) to the power of -1/2
The quotient rule being (bottomXderivoftop)-(topXderivofbottom) all divided by bottom squared?

By studying instead of posting my homework on Yahoo questions

Use the chain rule then the quotient rule.

I don't. It's your homework, not mine.
