(\partial)/(\partial y)(y^x-ln(x^4y+7x))

\frac{\partial}{\partial y} (y^{x} - ln (x^{4} y + 7 x))

x y^{x - 1} - \frac{x ^{3}}{x ^{3} y + 7}

Solution steps

\frac{\partial}{\partial y} (y^{x} - ln (x^{4} y + 7 x))

Treat

x

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial y} (y^{x}) - \frac{\partial}{\partial y} (ln (x^{4} y + 7 x))

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

\frac{\partial}{\partial y} (ln (x^{4} y + 7 x)) = \frac{x ^{3}}{x ^{3} y + 7}

= x y^{x - 1} - \frac{x ^{3}}{x ^{3} y + 7}

\frac{( 2 s + 3 )}{s ^{2} + 2 s + 26}

\int \frac{6 x}{1 - 7 x ^{2}} d x

2 x y^{^{'}} + y = 10 x

\frac{d}{d x} (\frac{2 ( - x ^{2} + 1 )}{( x ^{2} + 1 ) ^{2}})
