Integral de $$$\frac{\sqrt{13}}{x}$$$

Halla $$$\int \frac{\sqrt{13}}{x}\, dx$$$.

Aplica la regla del factor constante $$$\int c f{\left(x \right)}\, dx = c \int f{\left(x \right)}\, dx$$$ con $$$c=\sqrt{13}$$$ y $$$f{\left(x \right)} = \frac{1}{x}$$$:

$${\color{red}{\int{\frac{\sqrt{13}}{x} d x}}} = {\color{red}{\sqrt{13} \int{\frac{1}{x} d x}}}$$

La integral de $$$\frac{1}{x}$$$ es $$$\int{\frac{1}{x} d x} = \ln{\left(\left|{x}\right| \right)}$$$:

$$\sqrt{13} {\color{red}{\int{\frac{1}{x} d x}}} = \sqrt{13} {\color{red}{\ln{\left(\left|{x}\right| \right)}}}$$

Por lo tanto,

$$\int{\frac{\sqrt{13}}{x} d x} = \sqrt{13} \ln{\left(\left|{x}\right| \right)}$$

Añade la constante de integración:

$$\int{\frac{\sqrt{13}}{x} d x} = \sqrt{13} \ln{\left(\left|{x}\right| \right)}+C$$

$$$\int \frac{\sqrt{13}}{x}\, dx = \sqrt{13} \ln\left(\left|{x}\right|\right) + C$$$A
