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

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

e^{x}

Solution steps

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

Treat

y

as a constant

Apply the Sum/Difference Rule:

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

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

\frac{\partial}{\partial x} (e^{x}) = e^{x}

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

= e^{x} + 0

Simplify

= e^{x}
