  1. \(\dfrac{2^9 \cdot 3^9}{6^7} = \dfrac{6^9}{6^7} = 6^2 = 36\).
  2. \(\dfrac{18^7}{2^6 \cdot 9^6} = \dfrac{2^7 \cdot 9^7}{2^6 \cdot 9^6} = 2 \cdot 9 = 18\).
  3. \(\dfrac{7^9 \cdot 5^8}{35^8} = \dfrac{7^9 \cdot 5^8}{7^8 \cdot 5^8} = 7\).
  4. \(\dfrac{2^9 \cdot 5^{14}}{50^7} = \dfrac{2^9 \cdot 5^{14}}{2^7 \cdot 5^{14}} = 2^2 = 4\).
  5. \(\dfrac{100^8}{2^{15} \cdot 5^{14}} = \dfrac{2^{16} \cdot 5^{16}}{2^{15} \cdot 5^{14}} = 2 \cdot 5^2 = 50\).
  6. \(\dfrac{45^4}{75^3} = \dfrac{3^8 \cdot 5^4}{3^3 \cdot 5^6} = \dfrac{3^5}{5^2} = \dfrac{243}{25}\).
