Find the square root of $\sqrt{108 \times 2028}$.

$\sqrt{108 \times 2028}\\[1em] = \sqrt{108} \times \sqrt{2028}\\[1em] = \sqrt{3 \times 36} \times \sqrt{3 \times 676}\\[1em] = \sqrt{3} \times \sqrt{36} \times \sqrt{3} \times \sqrt{676}\\[1em] = \sqrt{3} \times 6 \times \sqrt{3} \times 26\\[1em] = (\sqrt{3} \times \sqrt{3}) \times 6 \times 26\\[1em] = 3 \times 6 \times 26\\[1em] = 468$

Hence, $\sqrt{108 \times 2028} = 468$.
