Step 1.1

Apply the product rule to $\frac{1}{x}$ .

$\int \frac{1^{2}}{x^{2}} d x$

Step 1.2

One to any power is one.

$\int \frac{1}{x^{2}} d x$

Step 1.3

Move $x^{2}$ out of the denominator by raising it to the $- 1$ power.

$\int {(x^{2})}^{- 1} d x$

Step 1.4

Step 1.4.1

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$\int x^{2 \cdot - 1} d x$

Step 1.4.2

Multiply $2$ by $- 1$ .

$\int x^{- 2} d x$

Step 2

By the Power Rule, the integral of $x^{- 2}$ with respect to $x$ is $- x^{- 1}$ .

$- x^{- 1} + C$

Step 3

Rewrite $- x^{- 1} + C$ as $- \frac{1}{x} + C$ .

$- \frac{1}{x} + C$
