Best ResponseYou've already chosen the best response.0\[\frac{dy}{dx} = \frac{x}{y^2\sqrt{1+x}}\]\[y^2dy = \frac{x}{\sqrt{1+x}}dx\]\[\frac{1}{3}y^3= \int \frac{u1}{u}du = \frac{2}{3} u^{\frac{3}{2}} 2u^{\frac{1}{2}}+C\]\[y = 2(1+x)^{\frac{3}{2}}6(1+x)^{\frac{1}{2}}+C)^{\frac{1}{3}}\]

Best ResponseYou've already chosen the best response.0OMG!I typed something wrong!! \[\frac{1}{3}y^3= \int \frac{u1}{\sqrt u}du = \frac{2}{3} u^{\frac{3}{2}} 2u^{\frac{1}{2}}+C\]
