解答ステップ

\int_{0}^{1} x (4 x^{4} - \frac{x ^{4}}{4}) d x

簡素化

4 x^{4} - \frac{x ^{4}}{4} : \frac{15 x ^{4}}{4}

= \int_{0}^{1} x \frac{15 x ^{4}}{4} d x

定数を除く:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{15}{4} \cdot \int_{0}^{1} x x^{4} d x

簡素化

x x^{4} : x^{5}

= \frac{15}{4} \cdot \int_{0}^{1} x^{5} d x

べき乗則を適用する

= \frac{15}{4} [\frac{x ^{6}}{6}]_{0}^{1}

限度を計算する:

\frac{1}{6}

= \frac{15}{4} \cdot \frac{1}{6}

簡素化

= \frac{5}{8}
