(\partial)/(\partial x)(x^7+3^y+x^y)

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

7 x^{6} + y x^{y - 1}

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

\frac{\partial}{\partial x} (x^{7}) = 7 x^{6}

\frac{\partial}{\partial x} (3^{y}) = 0

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

= 7 x^{6} + 0 + y x^{y - 1}

Simplify

= 7 x^{6} + y x^{y - 1}
