Step 1.1

Move the exponent $2$ from $\tan^{2} (x)$ outside the limit using the Limits Power Rule.

$\frac{{(lim_{x \to 0} \tan (x))}^{2}}{x}$

Step 1.2

Move the limit inside the trig function because tangent is continuous.

$\frac{\tan^{2} (lim_{x \to 0} x)}{x}$

Step 2

Evaluate the limit of $x$ by plugging in $0$ for $x$ .

$\frac{\tan^{2} (0)}{x}$

Step 3.1.1

The exact value of $\tan (0)$ is $0$ .

$\frac{0^{2}}{x}$

Step 3.1.2

Raising $0$ to any positive power yields $0$ .

$\frac{0}{x}$

Step 3.2

Divide $0$ by $x$ .

$0$
