Rewrite the exponent using the power rule $\frac{a^m}{a^n}=a^{m-n}$, where in this case $m=0$

The integral of a function times a constant ($6$) is equal to the constant times the integral of the function

Apply the power rule for integration, $\displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}$, where $n$ represents a number or constant function, such as $-2$

Simplify the fraction $6\left(\frac{x^{-1}}{-1}\right)$

As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
