G = \dfrac{{{{\left( {3.7} \right)}^2}{{.2.7.5}^3}}}{{{6^{2.5}}.6}}\\
= \dfrac{{{3^2}{{.7}^2}{{.2.7.5}^3}}}{{{6^{11}}}}\\
= \dfrac{{{{2.3}^2}{{.7}^3}{{.5}^3}}}{{{{\left( {2.3} \right)}^{11}}}}\\
= \dfrac{{{{2.3}^2}{{.7}^3}{{.5}^3}}}{{{2^{11}}{{.3}^{11}}}}\\
= \dfrac{{{7^3}{{.5}^3}}}{{{2^{10}}{{.3}^9}}}
