(\partial)/(\partial y)(2xy^4+2)

\frac{\partial}{\partial y} (2 x y^{4} + 2)

8 x y^{3}

Solution steps

\frac{\partial}{\partial y} (2 x y^{4} + 2)

Treat

x

as a constant

Apply the Sum/Difference Rule:

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

= \frac{\partial}{\partial y} (2 x y^{4}) + \frac{\partial}{\partial y} (2)

\frac{\partial}{\partial y} (2 x y^{4}) = 8 x y^{3}

\frac{\partial}{\partial y} (2) = 0

= 8 x y^{3} + 0

Simplify

= 8 x y^{3}
