解答ステップ

\int_{1}^{4} 4 x^{5} - 6 x^{2} - 7 x + 3 d x

総和規則を適用する:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{1}^{4} 4 x^{5} d x - \int_{1}^{4} 6 x^{2} d x - \int_{1}^{4} 7 x d x + \int_{1}^{4} 3 d x

\int_{1}^{4} 4 x^{5} d x = 2730

\int_{1}^{4} 6 x^{2} d x = 126

\int_{1}^{4} 7 x d x = \frac{105}{2}

\int_{1}^{4} 3 d x = 9

= 2730 - 126 - \frac{105}{2} + 9

簡素化

2730 - 126 - \frac{105}{2} + 9 : \frac{5121}{2}

= \frac{5121}{2}
