Solución detallada
  1. Integral xnx^{n} es xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

    xadx={xa+1a+1fora1log(x)otherwese\int x^{a}\, dx = \begin{cases} \frac{x^{a + 1}}{a + 1} & \text{for}\: a \neq -1 \\\log{\left(x \right)} & \text{otherwese} \end{cases}

  2. Añadimos la constante de integración:

    {xa+1a+1fora1log(x)otherwese+constant\begin{cases} \frac{x^{a + 1}}{a + 1} & \text{for}\: a \neq -1 \\\log{\left(x \right)} & \text{otherwese} \end{cases}+ \mathrm{constant}


Respuesta:

{xa+1a+1fora1log(x)otherwese+constant\begin{cases} \frac{x^{a + 1}}{a + 1} & \text{for}\: a \neq -1 \\\log{\left(x \right)} & \text{otherwese} \end{cases}+ \mathrm{constant}
