derivative of

e^{x} x^{7} + 14 e^{x} x^{6} + 42 e^{x} x^{5}

e^{x} x^{7} + 21 e^{x} x^{6} + 126 e^{x} x^{5} + 210 e^{x} x^{4}

Solution steps

\frac{d}{d x} (e^{x} x^{7} + 14 e^{x} x^{6} + 42 e^{x} x^{5})

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (e^{x} x^{7}) + \frac{d}{d x} (14 e^{x} x^{6}) + \frac{d}{d x} (42 e^{x} x^{5})

\frac{d}{d x} (e^{x} x^{7}) = e^{x} x^{7} + 7 x^{6} e^{x}

\frac{d}{d x} (14 e^{x} x^{6}) = 14 (e^{x} x^{6} + 6 x^{5} e^{x})

\frac{d}{d x} (42 e^{x} x^{5}) = 42 (e^{x} x^{5} + 5 x^{4} e^{x})

= e^{x} x^{7} + 7 x^{6} e^{x} + 14 (e^{x} x^{6} + 6 x^{5} e^{x}) + 42 (e^{x} x^{5} + 5 x^{4} e^{x})

Simplify

e^{x} x^{7} + 7 x^{6} e^{x} + 14 (e^{x} x^{6} + 6 x^{5} e^{x}) + 42 (e^{x} x^{5} + 5 x^{4} e^{x}) : e^{x} x^{7} + 21 e^{x} x^{6} + 126 e^{x} x^{5} + 210 e^{x} x^{4}

= e^{x} x^{7} + 21 e^{x} x^{6} + 126 e^{x} x^{5} + 210 e^{x} x^{4}

\int (x^{3} - 2)^{\frac{1}{7}} \cdot x^{2} d x

\int_{2}^{\infty} x e^{- 6 x} d x

y^{^{'}} (3 x + \frac{1}{y}) + 3 y + e^{x} = 0

\int_{0}^{1} 3 ln (4 x) d x
