\frac{d}{d x} (21 \cdot π \cdot x^{2})

42 π x

Solution steps

\frac{d}{d x} (21 π x^{2})

Take the constant out:

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

= 21 π \frac{d}{d x} (x^{2})

Apply the Power Rule:

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

= 21 π 2 x^{2 - 1}

Simplify

= 42 π x

y = ln (3 x^{2} + 7 y^{2})

\int csc (z + \frac{π}{4}) cot (z + \frac{π}{4}) d z

\frac{d}{d x} (0.02 x^{3} - 0.07 x^{2} + 8 x)

\frac{d}{d x} (cos^{4} (2 x))

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