c) $\frac{4^{6} \cdot 6^{4}}{3^{3} \cdot 8^{6} \cdot 15}$

Q: c) $\frac{4^{6} \cdot 6^{4}}{3^{3} \cdot 8^{6} \cdot 15}$

c) $\begin{aligned} & \frac{4^{6} \cdot 6^{4}}{3^{3} \cdot 8^{6} \cdot 15} \\ = & \frac{\left(2^{2}\right)^{6} \cdot(2 \cdot 3)^{4}}{3^{3} \cdot\left(2^{3}\right)^{6} \cdot(3 \cdot 5)} \\ = & \frac{2^{12} \cdot 2^{4} \cdot 3^{4}}{3^{3} \cdot 2^{18} \cdot 3 \cdot 5} \\ = & \frac{2^{16} \cdot 3^{4}}{3^{4} \cdot 2^{18} \cdot 5} \\ = & \frac{1}{2^{2} \cdot 5}\end{aligned}$$=\frac{1}{20}$
