integral from 1 to 2 of 5x^4

\int_{1}^{2} 5 x^{4} d x

31

Solution steps

\int_{1}^{2} 5 x^{4} d x

Take the constant out:

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

= 5 \cdot \int_{1}^{2} x^{4} d x

Apply the Power Rule

: [\frac{x ^{5}}{5}]_{1}^{2}

= 5 [\frac{x ^{5}}{5}]_{1}^{2}

Compute the boundaries:

\frac{31}{5}

= 5 \cdot \frac{31}{5}

Simplify

= 31

\int_{- 1}^{4} 4 d x

\int_{0}^{1} \frac{e ^{x} + 8}{e ^{x} + 8 x} d x

\int_{0}^{\infty} 6 x e^{- 3 x} d x

\int_{1}^{c o s (x)} 7 t^{6} d t

\int_{3}^{5} t^{2} + 2 t - 15 d t
