Problemddxx\frac{d}{dx}\sqrt{x}dxdx分步解答改写为幂次形式:x=x1/2\sqrt{x} = x^{1/2}x=x1/2。套用幂函数微分法则,n=12n = \tfrac{1}{2}n=21:ddx(x1/2)=12x−1/2\frac{d}{dx}(x^{1/2}) = \tfrac{1}{2} x^{-1/2}dxd(x1/2)=21x−1/2。改写回根式形式:12x\frac{1}{2\sqrt{x}}2x1。定义域:在 x>0x > 0x>0 时成立(函数有定义且可微分)。答案12x\frac{1}{2\sqrt{x}}2x1想解其他题?打开 derivative 求解器 →相关例题/solve/calculus/derivative-of-1-over-x/solve/calculus/derivative-of-ln-x
