\int_{1}^{4} \frac{( ln ( x ) + 4 ) ^{4}}{x} d x

Wende die partielle Integration an

= [(ln (x) + 4)^{4} - \int \frac{4 ( ln ( x ) + 4 ) ^{3} - ( ln ( x ) + 4 ) ^{4}}{x} d x]_{1}^{4}

\int \frac{4 ( ln ( x ) + 4 ) ^{3} - ( ln ( x ) + 4 ) ^{4}}{x} d x = (ln (x) + 4)^{4} - \frac{( ln ( x ) + 4 ) ^{5}}{5}

= [(ln (x) + 4)^{4} - ((ln (x) + 4)^{4} - \frac{( ln ( x ) + 4 ) ^{5}}{5})]_{1}^{4}

Vereinfache

[(ln (x) + 4)^{4} - ((ln (x) + 4)^{4} - \frac{( ln ( x ) + 4 ) ^{5}}{5})]_{1}^{4} : [\frac{1}{5} (ln (x) + 4)^{5}]_{1}^{4}

= [\frac{1}{5} (ln (x) + 4)^{5}]_{1}^{4}

Berechne die Grenzen:

\frac{1}{5} (2 ln (2) + 4)^{5} - \frac{1024}{5}

= \frac{1}{5} (2 ln (2) + 4)^{5} - \frac{1024}{5}

Vereinfache
