integral of x(10x+10)^{100}

Lösung

\int x (10 x + 10)^{100} d x

Lösung

1 0^{100} (\frac{( x + 1 ) ^{102}}{102} - \frac{( x + 1 ) ^{101}}{101}) + C

Schritte zur Lösung

\int x (10 x + 10)^{100} d x

Faktorisiere

x (10 x + 10)^{100} : 1 0^{100} x (x + 1)^{100}

= \int 1 0^{100} x (x + 1)^{100} d x

Entferne die Konstante:

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

= 1 0^{100} \cdot \int x (x + 1)^{100} d x

Wende U-Substitution an

= 1 0^{100} \cdot \int (u - 1) u^{100} d u

Multipliziere aus

(u - 1) u^{100} : u^{101} - u^{100}

= 1 0^{100} \cdot \int u^{101} - u^{100} d u

Wende die Summenregel an:

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

= 1 0^{100} (\int u^{101} d u - \int u^{100} d u)

\int u^{101} d u = \frac{u ^{102}}{102}

\int u^{100} d u = \frac{u ^{101}}{101}

= 1 0^{100} (\frac{u ^{102}}{102} - \frac{u ^{101}}{101})

Setze in

u = x + 1

ein

= 1 0^{100} (\frac{( x + 1 ) ^{102}}{102} - \frac{( x + 1 ) ^{101}}{101})

Füge eine Konstante zur Lösung hinzu

= 1 0^{100} (\frac{( x + 1 ) ^{102}}{102} - \frac{( x + 1 ) ^{101}}{101}) + C
