integral from 0 to 2 of (x^4+5)^3x^3

\int_{0}^{2} (x^{4} + 5)^{3} x^{3} d x

12116

Solution steps

\int_{0}^{2} (x^{4} + 5)^{3} x^{3} d x

Expand

(x^{4} + 5)^{3} x^{3} : x^{15} + 15 x^{11} + 75 x^{7} + 125 x^{3}

= \int_{0}^{2} x^{15} + 15 x^{11} + 75 x^{7} + 125 x^{3} d x

Apply the Sum Rule:

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

= \int_{0}^{2} x^{15} d x + \int_{0}^{2} 15 x^{11} d x + \int_{0}^{2} 75 x^{7} d x + \int_{0}^{2} 125 x^{3} d x

\int_{0}^{2} x^{15} d x = 4096

\int_{0}^{2} 15 x^{11} d x = 5120

\int_{0}^{2} 75 x^{7} d x = 2400

\int_{0}^{2} 125 x^{3} d x = 500

= 4096 + 5120 + 2400 + 500

Simplify

= 12116

\int_{0}^{\infty} \frac{x}{x ^{2} + 4} d x

\int_{0}^{1} (x + 5)^{3} d x

\int_{0}^{1} (1 - x^{2})^{6} d x

\int_{1}^{\infty} \frac{x}{x ^{2} + 9} d x

\int_{0}^{1} (1 - x^{4})^{10} d x
