Step 1.1

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

$\frac{\sin (lim_{x \to 0} 8 x)}{x}$

Step 1.2

Move the term $8$ outside of the limit because it is constant with respect to $x$ .

$\frac{\sin (8 lim_{x \to 0} x)}{x}$

Step 2

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

$\frac{\sin (8 \cdot 0)}{x}$
