Question

como derivar 1/√x+2 por favor

Answer 1

$( \frac{1}{ \sqrt{x+2} } )^{,} = \frac{(1)^,(\sqrt{x+2})-(1)(\sqrt{x+2})^,}{(\sqrt{x+2})^2} \\ \frac{0(\sqrt{x+2})-(\sqrt{x+2})^,}{x+2} \\ \frac{0- \frac{1}{2 \sqrt{x+2} } }{x+2} \\ \frac{-( \frac{1}{2 \sqrt{x+2} } )^,}{x+2}= \\ - \frac{1}{2(x+2) \sqrt{x+2} }$
