Решение:
\[ \frac{4 \cdot 6^{14}(2 \cdot 6^1 - 11)}{6^{16} + 3 \cdot 6^{15}} = \frac{4 \cdot 6^{14}(12 - 11)}{6^{16} + 3 \cdot 6^{15}} = \frac{4 \cdot 6^{14} \cdot 1}{6^{16} + 3 \cdot 6^{15}} = \frac{4 \cdot 6^{14}}{6^{16} + 3 \cdot 6^{15}} \]
\[ \frac{4 \cdot 6^{14}}{6^{15}(6^1 + 3)} = \frac{4 \cdot 6^{14}}{6^{15}(6 + 3)} = \frac{4 \cdot 6^{14}}{6^{15} \cdot 9} \]
\[ \frac{4}{6^{15-14} \cdot 9} = \frac{4}{6^1 \cdot 9} = \frac{4}{6 \cdot 9} = \frac{4}{54} \]
\[ \frac{4}{54} = \frac{2}{27} \]
Ответ: 2/27
