Step 1.3.6.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{2}$ as $2^{\frac{1}{2}}$ .

$\sin (x) = \frac{\sqrt{3} \sqrt{2}}{{(2^{\frac{1}{2}})}^{2}}$

Step 1.3.6.2

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

$\sin (x) = \frac{\sqrt{3} \sqrt{2}}{2^{\frac{1}{2} \cdot 2}}$

Step 1.3.6.3

Combine $\frac{1}{2}$ and $2$ .

$\sin (x) = \frac{\sqrt{3} \sqrt{2}}{2^{\frac{2}{2}}}$

Step 1.4.1

Combine using the product rule for radicals.

$\sin (x) = \frac{\sqrt{3 \cdot 2}}{2}$

Step 1.4.2

Multiply $3$ by $2$ .

$\sin (x) = \frac{\sqrt{6}}{2}$
