Question

how can i derivate the next function?

Answer 1

\[\frac{ 2x+4 }{ \sqrt{2x+4} }\]

Answer 2

do you know the quotient rule?

Answer 3

not at all :/

Answer 4

take a look at this:
http://en.wikipedia.org/wiki/Quotient_rule
theres a simple formula for it

do you know the chain rule?

Answer 5

Hint:
\[
\sqrt{2x+4} \cdot \sqrt{2x+4} = 2x+4\]So\[ \frac{ 2x+4 }{ \sqrt{2x+4} } = \sqrt{2x+4}
\]

Answer 6

mm i did the process step by step,, then i got = \[\frac{ 1 }{ \sqrt{2x+4} }\]

Answer 7

@wio, that was creative, i never would have thought to simplify like that

Answer 8

im fairly sure thats right @appleduardo

Answer 9

so am i wrong? mm

Answer 10
