(\partial)/(\partial x)(40sqrt(x))

\frac{\partial}{\partial x} (40 x)

\frac{20}{x}

Solution steps

\frac{\partial}{\partial x} (40 x)

Take the constant out:

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

= 40 \frac{\partial}{\partial x} (x)

Apply radical rule:

a = a^{\frac{1}{2}}

= 40 \frac{\partial}{\partial x} (x^{\frac{1}{2}})

Apply the Power Rule:

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

= 40 \cdot \frac{1}{2} x^{\frac{1}{2} - 1}

Simplify

40 \cdot \frac{1}{2} x^{\frac{1}{2} - 1} : \frac{20}{x}

= \frac{20}{x}
