\int_{1}^{3} x \cdot 4^{x^{2}} d x

Wende U-Substitution an

= \int_{4}^{64} \frac{u}{ln ( 2 ) \cdot 4 ^{\frac{l n ( u ) + 2 l n ( 2 )}{2 l n ( 2 )}}} d u

Entferne die Konstante:

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

= \frac{1}{ln ( 2 )} \cdot \int_{4}^{64} \frac{u}{4 ^{\frac{l n ( u ) + 2 l n ( 2 )}{2 l n ( 2 )}}} d u

Wende die partielle Integration an

= \frac{1}{ln ( 2 )} [\frac{u ^{2}}{2 ^{\frac{l n ( 4 u ) + l n ( 2 )}{l n ( 2 )}}} - \int - \frac{1}{8} d u]_{4}^{64}

\int - \frac{1}{8} d u = - \frac{1}{8} u

= \frac{1}{ln ( 2 )} [\frac{u ^{2}}{2 ^{\frac{l n ( 4 u ) + l n ( 2 )}{l n ( 2 )}}} - (- \frac{1}{8} u)]_{4}^{64}

Vereinfache

= \frac{1}{ln ( 2 )} [\frac{u ^{2}}{2 ^{\frac{l n ( 4 u ) + l n ( 2 )}{l n ( 2 )}}} + \frac{1}{8} u]_{4}^{64}
