Integraal van $$$9^{x}$$$

Bepaal $$$\int 9^{x}\, dx$$$.

Apply the exponential rule $$$\int{a^{x} d x} = \frac{a^{x}}{\ln{\left(a \right)}}$$$ with $$$a=9$$$:

$${\color{red}{\int{9^{x} d x}}} = {\color{red}{\frac{9^{x}}{\ln{\left(9 \right)}}}}$$

Dus,

$$\int{9^{x} d x} = \frac{9^{x}}{\ln{\left(9 \right)}}$$

Vereenvoudig:

$$\int{9^{x} d x} = \frac{9^{x}}{2 \ln{\left(3 \right)}}$$

Voeg de integratieconstante toe:

$$\int{9^{x} d x} = \frac{9^{x}}{2 \ln{\left(3 \right)}}+C$$

$$$\int 9^{x}\, dx = \frac{9^{x}}{2 \ln\left(3\right)} + C$$$A
