\(\frac{2(3a^2)^3}{a^6a^2}\) = \(\frac\){2(3\(\sqrt{12}\)^2)^3}{\(\sqrt{12}\)^6\(\sqrt{12}\)^2} = \(\frac\){2\(3 \cdot 12\)^3}{\(\sqrt{12}\)^8} = \(\frac{2(36)^3}{(12)^4}\) = \(\frac\){2 \(\cdot\) \(3 \cdot 12\)^3}{12^4} = \(\frac{2 \cdot 3^3 \cdot 12^3}{12^4}\) = \(\frac{2 \cdot 27}{12}\) = \(\frac{54}{12}\) = \(\frac{9}{2}\) = 4.5
