(\partial)/(\partial y)(x^{1/4}y^{3/4})

\frac{\partial}{\partial y} (x^{\frac{1}{4}} y^{\frac{3}{4}})

\frac{3 x ^{\frac{1}{4}}}{4 y ^{\frac{1}{4}}}

Solution steps

\frac{\partial}{\partial y} (x^{\frac{1}{4}} y^{\frac{3}{4}})

Treat

x

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= x^{\frac{1}{4}} \frac{\partial}{\partial y} (y^{\frac{3}{4}})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= x^{\frac{1}{4}} \frac{3}{4} y^{\frac{3}{4} - 1}

Simplify

x^{\frac{1}{4}} \frac{3}{4} y^{\frac{3}{4} - 1} : \frac{3 x ^{\frac{1}{4}}}{4 y ^{\frac{1}{4}}}

= \frac{3 x ^{\frac{1}{4}}}{4 y ^{\frac{1}{4}}}

\int_{- \infty}^{0} \frac{1}{4 - 8 x} d x

y^{^{'}} = \frac{x}{( 1 + 2 y )}, y (- 1) = 0

\frac{d}{d x} (cos (x) - 2 sin (x))

x \to 5 - lim (\frac{2}{x - 5})

\frac{d}{d x} (x^{2} y^{3} + x e^{x y})
