integral from 0 to 5 of 9e^{3x}

\int_{0}^{5} 9 e^{3 x} d x

3 (e^{15} - 1)

Solution steps

\int_{0}^{5} 9 e^{3 x} d x

Take the constant out:

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

= 9 \cdot \int_{0}^{5} e^{3 x} d x

Apply u-substitution

: \int_{0}^{15} e^{u} \frac{1}{3} d u

= 9 \cdot \int_{0}^{15} e^{u} \frac{1}{3} d u

Take the constant out:

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

= 9 \cdot \frac{1}{3} \cdot \int_{0}^{15} e^{u} d u

Use the common integral:

\int e^{u} d u = e^{u}

= 9 \cdot \frac{1}{3} [e^{u}]_{0}^{15}

Simplify

9 \cdot \frac{1}{3} [e^{u}]_{0}^{15} : 3 [e^{u}]_{0}^{15}

= 3 [e^{u}]_{0}^{15}

Compute the boundaries:

e^{15} - 1

= 3 (e^{15} - 1)

\int_{0}^{4} \frac{p}{9 + p ^{2}} d p

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

\int_{- 1}^{1} ∣ x + 2 ∣ d x

\int_{- 2021}^{2021} x^{5} d x
