(\partial)/(\partial x)(y^{x^y})

解答

\frac{\partial}{\partial x} (y^{x^{y}})

y^{x^{y} + 1} x^{y - 1} ln (y)

求解步骤

\frac{\partial}{\partial x} (y^{x^{y}})

将

y

视为常数

使用指数法则:

a^{b} = e^{b l n (a)}

y^{x^{y}} = e^{x^{y} l n (y)}

= \frac{\partial}{\partial x} (e^{x^{y} l n (y)})

使用连锁律:

e^{x^{y} l n (y)} \frac{\partial}{\partial x} (x^{y} ln (y))

= e^{x^{y} l n (y)} \frac{\partial}{\partial x} (x^{y} ln (y))

\frac{\partial}{\partial x} (x^{y} ln (y)) = ln (y) y x^{y - 1}

= e^{x^{y} l n (y)} ln (y) y x^{y - 1}

化简

e^{x^{y} l n (y)} ln (y) y x^{y - 1} : y^{x^{y} + 1} x^{y - 1} ln (y)

= y^{x^{y} + 1} x^{y - 1} ln (y)

y^{^{''}} - 4 y^{^{'}} + 4 y = t^{- 4} e^{2 t}

\frac{d}{d x} (\frac{x}{10} - \frac{10}{x})

\int 20 θ sec^{2} (θ) d θ

\int \frac{\frac{d}{1} ( x )}{x} d x
